== Names of Existing Businesses and Companies and Sites ( From the Game, some speculation ) :    ==
Would be used for Assets in Rapture ( even if just the old signs - some STILL might be working after all the years of neglect ).   Establishments would still be there in the Ruins.  New Assets would follow similar themes.  Some of these were just seen as signs out in the watery cityscape scenes.
NOTE - We don't have to throw out everything in that Canon-breaking Quantum-crutchified Infinitized DLC.
--- --- ---
== Business Establishments (ACTUALLY SEEN In-game) : ==
The 13th Muse Tavern/Pub - another bar that gave various Rapturites somewhere to go instead of sitting home watching The Telly.  Many were closer to the old time Saloons, which were more like social clubs.
""ADAM - New Used"  ( not sure how that 'Used' works )
Adonis Luxury Resort - (Pool & Spa) - full exclusive facilities for those who have to get away once in a while.  ( With Latest Vita-Chamber ? else why make a big deal of it, as they are all over Rapture, even in the seediest parts of the City ?? )
Asthetic Ideals (Steinman's ...)
Affordable Endings - another funeral home - even if there are no 'Taxes' in Rapture, there still is 'Death'.
Air-Tite Archives - secure storage for citizens.  Seen in Minervas Den. Presumably a convenient place to stash things away from the grubby hands of criminals.  Send * Receive * Store
Aloof Cat Food - maker of food for finicky cats (and hungry Splicers)
A-Mart - (Your Local Grocer) small 'convenience' shopping marts located throughout the city and suburbs.
American Dream - forget where I saw this (sign on a building).  Probably a 'trendy' clothing  store that copies current styles from the New York fashion market.
Anderson and Associates Consulting Engineers (BaS)
Andalusian Arms - BaS another hotel/apartment complex (spelling is suspect).  A bit odd because its normally known as a breed of horses (or a region in Spain)
Andrew Ryan Arms (from novel)
Annie's Tree Farm & Greenhouse - another Oxygen-regeneration business alongside decorative and commercial plant production.
Anton.  - one of those pretentious shops where a single first name is given ... ( for all we know it had the most popular brand of suppositories in Rapture )
Apollo Worldwide Airways System   ( ticket on luggage in Porter's bunker )
Apollo Argonauts Baseball Field - baseball venue for amateur as well as possible professional leagues
Apollo Argonauts Baseball Franchise - (semi-)professional team ( means there were several others in Rapture )
Apothecary  (Fort Frolic) in close proximity to Sander Cohen, it probably had a wide range of various 'recreational drugs' and other important products.
Arcadia - "Rapture's Playground" - "Rapture's Vacationland" - "Sylvan Wonderland" - "A Place to get away" - "Natures beauty at your fingertips" --- as close to nature as you get in Rapture(?). In the MMORPG it will be substantially larger than that claustrophobic caricature which was presented in the Solo games.
Arcadia Glens  - part of Arcadia (separate admission price, though they later had a 'park-hopper' ticket)
Artemis Suites - working-class residence in Rapture off the Apollo Square city cluster.  More typical stacked 'affordable' apartments.
Artisan Distilled Water - mid-range 'pure water' (joke is that in Real World you don't have to distill 'artesian water', so its probably the product of the city waste water recycling plant). Possibly became much more popular when Raptures water system started going downhill.
Artists Struggle - from Burial at Sea concept - not sure what it is, a posh Art museum/gallery ( likely of art that Ryan would approve of - alot of the art stuff (statuary, paintings ) in Dionysus Park was pretty tame, and might be also in this establishment).  Why you would need another (Dionysus) ? It was maybe more the venue of pretending to be "risque" and talked about - more the usual reason rich people buy their 'art'. Or simply it was a clearinghouse selling art in a retail fashion.
Athena's Glory apartments - "Lap of Luxury" - upscale apartments located off Olympus Heights
Atlantic Express, "Raptures Fastest Way to Travel" - Raptures Train/Subway system.  Converted to freight-only after a bankruptcy cause by a financial panic and consolidation of the City's Trolley and Bathysphere systems (Metro).
Atlantic Express Freight Service - bulk freight service to move the majority of Raptures materials.
Atlantic Express Locomotive Works and Manufacturing - company builds for the AE system, and does large machine manufacturing for other industries.  Foundries and machining.  ( The RR also is handy to move such large things to locations in the City. )
Atlantic Transportation Company  (original name for the AE system]] - when it was used to construct Rapture) Seen on blueprint in See Also AE Depot and elsewhere

AVA  - not sure what this actually is
Aveline's -  "Dresses for all occasions" "High Fashion from" ---  dress maker/seller in Rapture
Aventine Hotel - From Burial at Sea previews - another hotel ( not sure how many the city could support, but some rich people did actually live in 'Hotels' )

Bald Eagle Shot Shells - guns for the citizen - self protection is a right
Banks - not named but mentioned   ??????

Bistro - in MP Farmers Market - You think Starbucks was original ???
The Black Label Lounge  ( BaS building sign in exterior scene )
Blasich Smokables - Tobacco products do seem to be a popular traditional vice

Boutique Renata  - clothing (surface replica items available on request)
Bull ???  - seen in Neptunes Bounty MP - also seen in display window of "Tobaccoria" in Fort Frolic (so some tobacco or tobacco-like product).

Capotelli's (home made asparagus) -- one of those hydroponic vegetables grown in Rapture
Capt. Nemos - restaurant-bakery-patisserie  --- "I'd go 20000 leagues to get some of Capt Nemo's ..."
Cap'n Salty -- maker of most popular potato chips in Rapture (and own Potato Farming)
Central Square Bistro - good hub location in midst of high-end apartment complexes
Champion Pianos - "Finest Quality" - pianos were a sign of affluence and sophistication to the middle/upper classes
Chinese American Foods - restaurant
Chompers Dental - grade 2 quality rating ?? 
Christen & Smith Cranes  (seen in AE Depot in that weird 'switching hub')
"Cinema" - just that on a sign you see out of window in Fort Frolic near  Eves Garden.  They must show alot of old movies because it wasn't likely that many (good ones) would be made IN Rapture (ones that were worth watching) and there was TV also ( which knocked the movie industry for a loop in the Real World ).
Cinema Réal -  (with 4 screens!) - still showing the same pre-1952 movies
Circus of Values Vending  - maker of vending machines - everyday convenience at everyday prices
City Center - Commercial Space Rental ( 'location is everything' ... )

Coffee Bar - generic to the last
Cohen's Collection - Sander Cohen did things with plaster noone else did ...  Pushed the envelope ( probably into his victims eye ).   Rabbits and more Rabbits !    A business showroom (on second level) -- wouldn't that kinda go against the whole theme of Dionysus Park ??  But then 'by any means' for Sofia Lamb...
Corrective Genetics
Croft & Co - makers of the best 'crofts' in Rapture.
Cupids Arrow (BaS)
The Daily Bread (BaS)
Dandy Dental (dentist service)  probably even after ADAM Therapies available it would require a professional to control tooth regrowth and possibly cosmetic adjustments.
(Fontaine) Dandy Dentures  ( now with new mint flavor - defunct after ADAM Therapies were available (to regrow teeth) UNLESS there was some kind of technological apparatus included in the dentures that became 'trendy' -- ie- built in radio-phone or dictating machine or somesuch ).
The Daily Post/The Daily Times - Newspaper ( actually is from outside Rapture ) ( folded stacks seen in Eves Garden MP -- many of them - likely NOT from The Surface ?? )
De la Plante Tools - "the Best" - Maker of the Famous 'Wrench of Doom' which Jack 'The Atlas Slayer' swung.
Demeter's Banquet Hall (at Adonis Resort) - Le Cordone Bleu quality -- at a price the hoi polloi can not afford
Demitasse, "an urge for tea" ( Heh, I remember the Forum posting where they thought this name was gonna be a significant plot character in BS2 - turned out to be 'just a building sign' for a tea shop.....  tempest in a teapot by the fanbois - as they say. )
D. Francon Antiques - lotsa antiques brought to Rapture
Dionysus Park & Gift Shop - one of Sofia Lambs little cover operation for perpetrating her collectivist delusions and mass murder.
Do Tell  (BaS) ???? Newspaper or Broadsheet
Doc Hollcroft's (product and Pharmacy) a low end cure-all that at least did contain some ADAM (and probably alot more of the cheaper EVE).   Not quite as bad as the bootleg ADAM makers - he had a reputation after all to protect ( "Blind you only for a few hours, Guaranteed !!!"  citizens/relatives usually did things to quack sellers of poisonous 'medicines' ).   Dr. Hollcroft's Cure-All and Pick-Me-up
Dr Lamb's Therapy Office ( yet another front for her machinations to poison the minds of Rapturites )
Professor/Dr. Langford Research Laboratories ( agricultural technologies - responsible for many flora genetic advancements like lowering the cost of Oxygen regeneration ).
Dr. Steinman's Aesthetic Ideals ( cosmetic surgery for those who could afford it )
Dr. Suchong's Free Clinic ( part of one of Fontaine's subversive "fronts" and a channel for "volunteers" for testing, and 'counseling' to generate new 'orphans' ).
Dupuis Produce Company ( lots of produce for the population - lots of farms somewhere to provide it )
(The) Egean (seen on sign)
El Ammo Bandito ( ammunition at your convenience, ammo mundane and exotic ).
El Dorado Lounge ( classy destination to bring in more customers to Ryan Amusements - hangout of the movers and shakers and various Posers - at least as long as Ryan kept putting in appearances... )
Electronics - Seen in Burial at Sea preview - doesn't sound 40's theme-ish enough terminology to match the rest of the place - They could have come up with something better ("Electromatics" - took me all of 5 seconds for THAT one term ... )
Elizabeth Music Hall - another entertainment venue, possibly having that British Music Hall feel for all the Brits who came to Rapture.
Enwell Life and Health Group - health insurance - "Is your family protected?" insurance is all part of the modern business world.

Fighting McDonagh's Boxing Ring ( in the New Establishment ).
Fighting McDonagh's Tavern - we have both the original and the MP ones to go to.
Fine Shoes - seriously, would people want crappy shoes ?
Fin De Siecle Boutiques (BaSx) - A nice presumptuous name is allowed to the inhabitants. "End of the Century" when they are barely halfway thru the current century begs the question whatall do they sell ? Properly styled things actually take talent ( even just to product product ), and it wont be massproduced - so will be expensive. 1950s Space Age theme ( stealing styles from The Surface - somehow obtained after the serious restrictions on Surface contact ). That Giant (gianourmous) lit building sign for a 'shop' ?? Good way to piss away profits for something barely seen out in the water. 
Finley's Eat-In Take-Out
Finley's Pub - has those big signs out in the sea we keep seeing.
Fishbowl Diner (Paupers Drop eatery - not exactly a 'soup kitchen' for the indigent)
Flanagan P.I. - with normalcy gone and murderous crimes everywhere, who needs a P.I. to find out whats going on??

FONTAINE creams • pills • injections ( another big sign on exterior view )
Fontaine's - BaS  some kind of club (besides that dim 'mall' place in BaSx).

Fontaine Clinics,  Fontaine Blood Donor Clinics ( wanna bet they proscribed ADAM products for more than a few maladys ... )
Fontaine Dandy Dentures (??)
Fontaine Field - a sports venue (its name sold as is common these days...)
Fontaine Fire Fighters - possibly like Crassus, his firefighters would show up but then he would bargain with the building owner ( and nearby building owners to which the fire might spread ) to sell it cheap before it burned down, and ONLY THEN his firefighters would go to work ...
Fontaine Fisheries - consolidated from many fishing companies Fontaine strong-armed from their owners.
Fontaine Fruits - probably another business extorted and strong-armed away from its original owner.
Fontaine Futuristics - source of multiple high tech products in particular ADAM  genetic products
Fontaine Hi Power Ammo - likely a cover for his eventual plans to take over Rapture
Fontaine Packaging Corporation - seen on some crate wood.
Fontaine Pharmaceuticals - too bad Fontaine didn't come up with a cure for the nasty effects of his other product.

Garden of the Muses - mentioned in BaS
Gardner's Deluxe Modern - its modern, its deluxe, its wrecked by the time we see it.
Gatherer's Garden  - was this actually a separate company ( a division of another company ) ??  Ryan talked of Fontaine being inept at marketing, so this may be a pre-Fontaine-death development ( gets a bit ridiculously tight if it was after the seizure - only months before the Kashmir Incident and all the following 'disorder' ).
Gaynor Produce Corporation - big producer of produce/fruit  fresh and canned
Genetic Horizons -   Splicer mentions 'Fresh Hair' ( tonic made/sold by this company ) before going to Steinman to change his image to try to get some 'ladies'.
"Genuine Sea Salt"  on chips ...
Glaustein Thermoses - maker of those coffee Thermoses you see all over Rapture ( how many of them actually had coffee in them and what else might there have been ?? )
Golden Rule - an upscale bar ? From Burial at Sea concepts
Good-Eats -  must be doing good business to be able to afford so many advertising signs.
Greenfields  - Inflatable Toys - possibly not just for children ...
Haas Classy Clothes - "Nothing Finer for the Gentleman of Discerning Tastes"
Hacksmart's  (Plasmids/Tonics) - Hacking isn't exactly legal, but perhaps such abilities also had common utility in the workplace.
Hall of the Future ( part of Ryan Amusements, though like at Disneyland many of the attractions were paid for by Sponsors, a very clever business arrangement )
The Hamilton (Office Space for Rent) - in Paupers Drop - a typical Noir setting

Heller News  (daily and evening editions)
Hephaestus Power Facility - largest utility company in Rapture.  Provides Electric Power, fresh water, and Heating (via hot water).  May provide flammable gas products also (and oxygen).

Ingram Lock Company - Rapture's best known combination door locks
Jack Bros. Ply Ltd (proprietary limited)
Jack Frosts Village - A whole mini-mall that you skate around in - THAT might've been a neat idea (just because its in lame DLC doesn't mean the idea can't be improved and used in the MMORPG)
Jemco Foods Division  (maker of Beef-E)
Jet Postal - the 'Pneumo' mail system -  "Delivered in a Flash!"
J. Fischer Gallery - Schrödinger's Cat says : "Is the art good or bad ? It is both until you open the box !"

Joe's Green Groceries - Meanest vegetables in Rapture
John and Welch Holding Co. - A holding company is a company or firm that owns other companies' outstanding stock.   So was there much of a stock market or was it more bank organized investment shares in businesses?

Laplante   - metal tools ?? On the side of our favorite Wrench
Laurel Boutique - Stylish Ladies clothes ( including "Surface Replica items available on Request" )
Le Marquis De Epoque le Marquis D'Epoque ("Fine Liquors and Tobaccos") - no doubt various 'cocktails' of ADAM products were found to give the best 'experience'  ( and why not in combination with some old school 'dope' ?? )
Lentz Bijoux & Bibelots -- "bibelot" = a small household ornament or decorative object
Le Temps Perdu - "Lost Time" - from Burial at Sea - looks like a high priced boutique bar
Liberty Cartwidge Ltd ( Ltd = Limited Company -- a company in which the liability of members or subscribers of the company is limited to what they have invested or guaranteed to the company. )
Liberty Cartridge Co - not to be confused with ^^^, sounds like another gun related shop ( really strange if it was a candy shop ... )
The Limbo Room  - The Deep Blue Revue, Full Bar ( serves meals but no sign of a kitchen )
Lisa's Candies  - Gifts, Sweets, Malts
Little Sister's Orphanage - Fontaine's source of raw material for new blood sucking little ghouls.

Mermaid Bar  (? in Adonis -- one in Sirens Alley)
Mikro's Brewery  
Monadnock Travel Services - Baby sitters -- how much travel could there be in Rapture ??
Monarch Fisheries (trademark Approved) - Another grab by Fontaine. Seriously how could Fontaine's thuggish practices be covered up for so long in a place as small as Rapture ?  And NO, its not allowed under that idiotic 'No Laws' thing the authors perpetrated.
Mo's Diner - Pats, Burgers, Hoagies, Beer, Swid, Grinders, Chicken
Nate's Guns & Ammo , Targets - Guns and ammo are allowed to the citizens, who have ultimate responsibility for their own safety.
Neckties by Wilson Freeman - A standard item for that era - silk neckties ? Silkworms and Mulberry trees in Rapture ?
Nevr-Wet Waterproofing - Probably expanded business when many of the original building produced chronic leakage, versus originally a being a vendor for workmen in wet environments.
New Century Publishing Ltd. - One of many book and magazine publishing companies. With a smallish population there would be many niche markets for published goods.
New Worlde Smoker (Pipes and Cigars To Your Health ) - Some businesses brought large stockpiles of goods with them to Rapture, enough to keep selling for decades - especially the more esoteric varieties preferred by aficionados
News  ( Franchise media stand found in may locations especially train stations )  Magazines/newspapers/candy etc for commuters
Night Club Casino ( seen off in distance in one of cityscape views ) - yet another casino. How many could you have in a City of only 20000 to 40000 people?  Must've have competing gimmicks like Las Vegas/Atlantic City do these days.   Nightclub component probably would be important draw for customers.
Nini Lyons - Toys - low end toys and 'collectibles'
Oceanview Pharmacy - In Sirens Alley area, probably dealt more in similarly themed products after the construction boom was over.
The Odeon ( Seen in BaS - name often for a Theater) - Famous greek theater in ancient Athens - so for Rapture ...
Open Plasmids - Another Plasmid product competitor. Reverse engineering and knock-offs were common ( and often the result of employees who weren't paid enough and set up their own companies )
Olympus Heights apartments - located in the upper-class residential district with high-end appointments and convenient access to transportation for the influential residents.
Optimized Eugenics - Fontaine's main testing and researching facility at Point Prometheus
OXY FILL Gas - Seen outside in the water, so there must've been various non-maintenance divers all about out there.
Painless Dental ( We are There When It Hurts ) and the Kure-All clinic - pays to advertise and people aren't overly patient to search for a dentist when they have a toothache. Oral Surgery ...
Paradiso Cafe/Coffee Bar -  A bit of paradise at the bottom of the sea - imagine thousands of Caffeine addicted Splicers when the Coffee ran out ...
The Pearl (Hotel) aka. The Pink Pearl - just about anything goes in Rapture - Pope Hats on request ...
Persephone Correctional Facility ( Detention Facility, Penal Colony ) - yes like most things in Rapture it was a 'business'.   Likely served as jail for short term criminals as well as a prison for those proven unwilling to live within civilized law.  It may also have had an insane asylum fro the criminally insane  - something there was a growing number of in Rapture after ADAM was introduced.
Pham Pneumo ( Seen on equipment, possibly a subcontractor )
Pharaoh's Fortune Casino - "We Play For Keeps" - 2 Drink Minimum  --- those signs must've been fairly cheap (and the power to light them up) for such small establishments to have so many.
Piano Bar (Dionysus Parks place to be seen - how did they keep the hoi-polloi from mobbing the place ??)
Pin Money Women's Apparel  ( incidental expenses - selections for the frugal )
PlasmaQuiks - Gene Banks - actually would have been very high-tech genetics to activate/deactivate Plasmids and Tonics.
Plump Mussels "Delicious Deep Diving Dinner"
Poisoned Apple - Evil Queen presides ?  Not exactly an image for a bar I would want - Golden Apple maybe ?
Poppadopolis Police Department - "The RIGHT Police Department", "Don't trust your family's safety with the WRONG police department" - Private police service to surpass the 'Constables' normal level of protection.  ( Odd wording, as how can these be 'Departments' if they aren't official ?? )
Power to the People ( machines to upgrade weapons - must've been alot of standard weapon types ), Fontaine product - first installed 1/21/57.  Machines may actually have been installed widespread in Public AFTER Fontaine was dead and Ryan had them positioned so that common Citizens could arm themselves against Atlas's murderous mutants.
Pret-n-Porter  ? Pret-A-Porter - some sub-store seen in BaS preview  (just a doorway)
Pringle's Garage and Gas ( for submarines or for rich peoples automobiles - yes there could be those )
Radio Action - Another radio station with news/entertainment (and advertisements)
The Railway Cafe - Food for workers in the AE Depot ( Cafeteria would have been better and a 'Railway Cafe' up at the station for the passengers ).
Rapture -- Alot of utility equipment/machinery has this single logo - made in or for Rapture ( pre-made on The Surface )
"Rapture" - For what looks like a produce company with "Rapture Certified" - Maybe its for the 'certification' business  (kind of like Underwriters Laboratories, listing, testing, rating, etc ... )
Rapture Alarm Systems ( Another security measure that businesses could add for additional security )
Rapture Central Computing Corporation - "RCC" - ( very profitable as the computer industry was in the Real World, because of the accounting/clerical labor it replaced/made-efficient ).
Rapture Colony - Entity designation for various official interactions  ( --- "Rapture Sea Community" seen on sign for Sterner Brand Sea Meats )   Possibly designator of "Rapture Certified" status.
Rapture Crown ( Cocao beans and Sugar Cane production - specialty farming )
Rapture Film Productions (BaS)
Rapture Firing Range  ( Practice for sport or self-protection, included a gun store )
The Rapture Flour Refg. Co  ( refrigeration ..  storage - probably equivalent of grain elevator storage , 100% organic )
Rapture Gas  - Gas for all the various things that needed great heat - Rapture's primary environmental heating was via the Hephaestus Geothermal system (Hot water distributed thru the City)
Rapture's Grand Carnival ( a popular spot for amusements. Important would be a cycling selection of different attractions/themes so it would be different every time you went. ) TV celebs can have their second jobs ...
Rapture Herald - Newspaper ( another news outlet - with so many newspapers they have to have some differentiation between them in style and content )
Rapture Medical Group ( Association probably with a mandate to maintain standards for members - Premium Care Service )
Rapture Metro ( consolidated - Bathyspheres for the 'high end', and Citywide Trolley System for the proles )
Rapture Museum - Presentation of the vision and effort which went into building Rapture.
Rapture (Oil) 55 gallon drums (synthetics)
Rapture On Ice  (BaS)  (an Ice Rink)
Rapture Open, Tennis Tournament  ( of course its a business ),  venue probably was Rapture Stadium
Rapture Radio  ( Not sure how many stations frequencies there are - possibly many (dozens) in competition as the actually infrastructure for additional stations was not that expensive ) Provided thru Rapture's coax cable network.
Rapture Records - Vinyl disks with approved (imported) Surface content, and new releases by talent in Rapture.
Rapture Savings Bank - from concepts, but a logical addition as a place for people to keep their money and as a source for small loans, etc ...
Rapture Standard - Newspaper ( one of these newspapers would have a financial specialization - can't have too many general newspapers in such a small city )
Rapture Tribune - Newspaper ( another might be 'society' or sports or pop-culture ... )
Rapture Vineyards ( possibly an association to define Wine/Brandy standards )
Rapture Zoo & Giftshop - How do you fit an elephant into a Bathysphere ???
Rational Sowing Machines and Service   ( sowing or sewing ?? either way rational is a strange adjective for those )
Reliable Pharmacyhttp://rapturearchives.org/img/ads/ad_reliable_pharmacy.jpg - Ryan's commercial chain for selling medical products and sundries/canned goods (diversification) - "Convenience and Fair Pricing the Ryan Way"
Roark Architect & Construction ( competition for Wales Brothers - probably made buildings that didn't leak )
Robertson's Tobaccoria ( big signs - big business - Big addiction - caused Samurai in 17th century Japan to threaten to kill their leaders if forced to stop smoking ).   Had to have local source in Rapture, big public operation could not operate off 'smuggled' tobacco products.
Rock Flanagan PI - Office in Paupers Drop. Business went downhill when the 'Mean Streets' of Rapture got alot meaner with Fontaine/Atlas's Splicer anarchists terrorizing them.
Rork Key Co. ( Keys = Locks = Security -- 'No Laws in Rapture' wasn't really true, and all populations have some criminals )
Ryan Amusements  &  Gift Shop ( MMORPG would have a few more 'amusements' there and I would add various 'collectables' to sell amongst other things )  
Ryan Brewing Company - Ryan believed in competition, and was ready to give it ( it helps to keep standards up ).
Ryan Club Beer Ale - Tap Tap for R. C. - Tastiest Beer in Town  ( someone has to grow Hops in quantity for all the beer we see advertised )
Ryan, Computer Equipment   ( ?? keypunch seen in Minervas Den )
RYAN Official Retailer | ADAM bought • sold | implants • enhancements | extend your life | your source for ADAM legal • clean • safe  ( big sign - big business )
Ryan Industries, INC   ( parent company for many of Ryan's commercial ventures )
Ryan Industries Brewery - A collaboration with McDonagh
Ryan Labs - New and better products take Research - probably took off after Brain-Boost became available
Ryan Manufactories - Lots of things to make in 'self-sufficient' Rapture. Consolidating know-how and infrastructure is one way to be competitive in a world of small markets for products.
Ryan Pharmaceuticals http://rapturearchives.org/img/ads/ad_reliable_pharmacy.jpg- Being at the bottom of the sea didn't prevent people from becoming sick or thinking they were.
Ryan Red (Wine) - All these vineyards had to be someplace - Rapture was alot larger than the tiny bits we saw In-Game ...
Ryan's Raiders - Football Franchise - how many teams would you need for a league ??
Ryan Scrap Metals - Recycling was profitable when many materials had to be obtained at greater expense.
Ryan Security - For Ryan's own holdings and anyone else who wanted additional service.
Safe Batteries - For lots of battery powered devices in Rapture
Salty's Chips Company - Potatoes grow pretty good even in miserable environments in Mars dust and human excrement - in "The Martian" . - so these would likely be made with real potatoes.
(The) Satyr - seen in Burial at Sea - Some night club ??  - The Satyr Lounge  ??
Scallop Spirits
Schneicher Optics - Optical glass and lenses for many different products - cameras/sensors/tourist pay  binoculars...
Science And You Magazine - Another periodical with a science concentration - likely an important vector for announcing new whizz-bang products.
Sea Bulls Football Franchise - Another team - sports must've got very odd when splicing started.
Seabed Brewing Company - Another fine provider of one of Rapture's most popular products - beer (Poseidon Pilsner).
The Sea Horse - Exotic Dancing Club in Fort Frolic.  There should have been others not as 'high-class' - one likely in Paupers Drop. 
Seaworthy Construction - Another competing company to Ryan's.  Many millionaires came to Rapture, and alot of their money went to build the city  (would have been hard with just Ryan's money by itself to make it so large).
Securis (water tight doors) ubiquitous doors seen throughout Rapture. One of the primary safety systems to close off flooding sections.  Would have been much more reliable than many we saw in the Solo games.
Shock Comics - No Comics Code Authority to regulate comic books in Rapture.  Of course with such a small population, there wouldn't be so many different ones.
"Shubert Theater"
Silk Lounge (in Kashmir) - A Place for the hoity-toity to get a snoot-full  "Good Friends Meet at ..."
Silver Palace Bar - It is silver and a palace, and they serve drinks
Silver Fin Restaurant ( BaS in Fontaine's mall named a Department Store Department Store - A large store stocking many varieties of goods in different departments. Usually under one owner. )
Silverwing Apiary - Bees being important to various crop production, there would have to be alot of Bees for Rapture'e agriculture. Suitable types were found or later modified genetically to work in Rapture's environment.
Sinclair's  -  Beer, wine, liquors, cheese (retail)
Sinclair Deluxe - "Affordable housing for those on a welders wage" - actually not a bad looking place ( the run down/ruined look was result of it being under 'new management' ).   Sinclair saw a market and redeveloped part of Paupers Drop for a particular low-end clientele.  'Whiney' Audio Diary talks of having to deal with Sinclair - Sounded like someone who didn't want to actually pay to stay in 'The Deluxe'.   "The most modern of lower Rapture's accommodations" - being in the Southern 'old' section of the City ??
Sinclair Metals/Sinclair Scrap  ( "Raptures Best" "One Mans trash is another Mans Treasure" ) -  Scrap salvaged and towed in from wrecks (one good wreck might have thousands of tons of steel -- wreck (or chunk of it) might be towed closer to rapture ( and shallower location ) using the sea-lift balloon technique.
Sinclair Solutions - Produced Sinclair Solutions Tester Pack, amongst other products ( including prison accessories ... )
Sinclair Solutions Cosmetics (subsidiary)
Sinclair Spirits - Not all Paupers Drop quality, since you see his fancy store in Poseidon Plaza
Sinclair Toy Company  ( Sinclair Toys - "Just because they are made out of Junk doesn't mean they aren't fun" )
Sir Prize (casino) -- How many casinos could Rapture accommodate ?  Yet these are not that large an establishment in reality.  ( Rapture's casinos could FIT in the Mens Rooms in some of the Mega-casinos of today. )
(Dr) Sofia Lamb's Therapy Office, Psychiatrist -- Sofia Lamb knows ALL about delusions...
Soho  "Ho Ho for Soho"  - Still not sure what it is sounds classy, which usually means expensive
Song Bird (Sound)  - ? A music producing/publishing company
Sonia Fine Modern - New designs brought in from The Surface ( and maybe some held back for later when Ryan's cutting off was to take effect).  Brain Boost possibly made all kinds of Rapture-made interesting and actually aesthetic designs possible.
Sonorous Inc - Seen on Burial At Sea preview - record store ( possibly a publishing/recording company also ) - Now with Stereo !!!
Sophia Salon, High Fashion (Sophia Salon Sale) - even in the depths of the ocean, fashion can be 'high'..
Spenser Investigations - Big enough to have large neon sign outside building in ocean ( but then maybe that wasn't so expensive - and being Rapture we should have almost had many of the buildings covered in them ... )
Steinkamp Recordings - Vinyl records including Grace Holloway
Steinman's - General medical practice, cosmetic enhancements - "We Care for You"
Steinman's Rhinoplasty  (Nose surgery - largely cosmetic.  With new techniques it still requires artistry)
Stingers Football Franchise - Another team in the semi-pro league ( so there must be a football stadium - and none of that 'indoor football' stuff either ).
Suchong Institute and Suchong Laboratories - Suchong's company contracted by Ryan Industries and Sinclair Solutions (and Fontaine). (( Or just "Suchong Laboratories" ))
Sunset Meats (and Poultry)  "Raptures Finest"
Surgical Savings - Medical loans 
Tasty Plate - Surface style cooking  ( with surface or non-surface ingredients ?? )
Tate Wineries - Owned by actress who collaborated with Sander Cohen - Merlot wine product
Tea Garden (in Arcadia)  -- The Tea Garden was one of the most romantic places in Rapture (allegedly).
Tea Time Cafe - ( Coffee, Tea, Pastries, Biscuits ) "Come and have a Cup" -- Little old ladies needed somewhere calm to go when shopping - unless it isn't that kind of 'tea'...
Thanks Mom ! brand  ( Cream filled chocolate cake ) - tasty and healthy ...  healthy ? Maybe if compared to eating paint chips off the walls...
Thomason Tobacconist ( Smoking still a big thing - big advertisements aren't free after all )
Thrifty Care - Competition and new medical methods would shake up the medical business. Affordability now for many who in the realworld at that time didn't have much systemic medicine ( Doctors still made house-calls )
Tickets - Movies Theater Plays (Call for showtimes) - ticket service agency
Tip-top Security ( on of many private security businesses )
TOM & DAVE hired guns • contracts • paintings
Top Coat - "You cant top Top Coat"  - another sign out on the buildings
Tree Farm - A bit generic name-wise but gets its point across ( there were MANY tree farms run as businesses )
Triton Theater/Cinema - In Dionysus Park, attracted many citizens because of the exclusive movies owned by members.  Facilities included a film studio and process facility.
Turing Room Bistro
Twilight Fields Funeral Homes - People are dying to get in - how much you wanna bet recycling ADAM became a sideline??
United Seafloor - Construction company - later a big Player in the growth of the suburbs with the inexpensive rock cutting of tunnels and caverns.    Also producer of products like 'Calci-O'
Uptown (club)
Value King - Convenience store -  sundries for the masses, producer of Meal-Time Frozen Dinners
Vita-Stat Medical Goods - Business probably took off after the ADAM-based medicines came into being - "Sawed a finger off ?  No Problem. Apply a Vita-Stat Medi-kit and be Right as Rain !! -- Now in Suppository Form !!!"
Wales & Wales Architects
The Watched Clock (BaS)
Water Treatment Station ( Would have been run as a business/service ?   Particularly for better than 'normal' Rapture utility water )    Rapture Sewage Ltd ?
Weissman & Co. (white flour) - Sander Cohen had to switch to plaster, the bugs kept eating his 'flour' based  artwork.
William Strong Vitamins ( minimum would be Vitamin D for sunless Rapture )
Wilson Freeman -  Neckties - "Top Quality, Top Value" -- Pseudo Silk ties for the adequately well dressed
Worley Winery/ Worley Distillery ( more booze to assuage that closed-in feeling people get in Rapture )
Zimmerman Chardonnay (since 1951) - someone must have grape plants in Rapture to go along with all the other farming required to create the food a city eats.

Burial at Sea ? :
Twilight Fields Funeral Home price board has 'Burial at Sea' listed -- Isn't that a bit weird when that usually is just dumping the corpse into the ocean in a shroud ( usually combined with chain or something heavy to make sure it sinks/stays on the bottom ). So somewhere near Rapture you will find a bunch of corpses sitting there on the seabed with fish nibbling on the corpses ... Maybe they at least cover you up with silt ( another interesting 'setting'/scene for the MMORPG --- the underwater graveyard (haunted or haunting) ?? Lots of space for monumental grave markers ). Hmm, torpedo launch funerals like the end of Wrath of Kahn ??
--- --- ---
Abyss :
The Abyss is a isolated pocket ecology cause by a collapsed magma chamber on an ancient volcano ( Sea Mount ) which inside drops to a significant depth of 4000+ feet. The volcano's rock structure completely surrounds/encloses it at a depth of only 1000 feet or less.
Geothermal activity within the old volcanoes structure heats the region well above the normal freezing temperatures of the local ocean water, allowing greater diversity of life to survive ( lucky for us to be able to go visit it ).
Unusual Bioluminescence activity in 'the Biomass' ... ( like weird glowing things and mutant Sea Slugs ).
Various resources were taken from the Abyss, several useful minerals, flame coral, Sea Slugs, bioluminescent materials, all gathered by remotely controlled mini-subs and machinery ( with manned subs only being sent down to fix something ).
Likely Business : Tourists descended to various depths in a special deep dive sub to view the unusual glowing growth formations and Sea Life.
Eventually (as New Rapture expands) the Abyss will play its part in quests/missions.
--- --- ---
Rapture Stadium - Sporting Events and Exercise Area (Swimming Pool Also) :
Interpolated - You have to play games for the game-mentioned teams somewhere.
* Even if they don't have enough teams for a 'proper' League, also facilities still could be used for exercise, Polo (?)
* Probably would have to be a large cavern. A large glass ceiling likely wouldn't get you much except higher expense ( and its too dark at the depth to see much anyway).  Ceiling reinforcement and pillars probably needed as the cavern may have to span 300+ feet of open space ).
* Would have an Atlantic Express station to handle the crowds ( They would probably want 2 Trolley stations as well ).
* Baseball would be even more popular than football ( size limitation might mean MORE 'home runs' being likely ).
* Crackerjacks have not been seen in Rapture for over 15 years, and you don't really want to know what the 'hotdogs' are  made of. Beer is again available.
* There must be a golf course somewhere in Rapture too, and tennis courts.
* General use of the facilities with A Sports/Exercise Membership ( It is not a charity you know ...)
--- --- ---
Annie's Tree Farm & Greenhouse :
There should have been lots of these agricultural businesses, which many people would have the skill to do ( including many who only thought they did whose failed businesses then went to someone else ).
Trees do take a while to grow, but there are quick growing varieties, and other plants which grow far faster - to be used for oxygen generation ( actually scrubbing carbon dioxide from the air ) and biomass production, as well as also producing food (including animal food for livestock/pets). Wood ( and fiber pulp for paper ) from trees/plants is another product.
Heating and light equipment and water and nutrients are needed to grow plants ( wasn't it smart that Sinclair bought-up/built Sewage Farms in Rapture ? )
Sorry, no "Feces King brand Potatoes" ( ala "The Martian" ) - Whether true or not, its just TMI for the customers. Actually that reminds me : that they grow common mushrooms in sterilized cow manure ( didn't you know ? ), so that's another kind of 'farm'.
--- --- ---
"Need Cash - Donate Blood $$$ - Fontaine Clinics" :
Convenient way to obtain human biological matter for experimentation ( Possibly get some ADAM back too ), or at least to use the Blood to train the Little Sisters - It takes some skill to drink blood that fast without gagging ...
