I wouldn't call myself a fan of fish tacos--that is, until I tried the ones here!  I stopped in last Sat. with some friends before heading over to the Grape Stomp at PGH winery, since this place had been highly recommended by a couple of other friends of mine who have good taste in food.  Unlike just about every other fish taco I've had, the fish in these was fresh and flavorful!  As Lauren B. mentioned, it is a combination of swordfish, tuna, and salmon, instead of the generic white fish that's included in most other fish tacos I've tried elsewhere.  The presentation of the tacos was also quite aesthetically pleasing, which was a plus.  If you're a fan of fish tacos, you have to try these!  Come by on Taco Tues. if you can for a discount.\n\nMy friends ordered crab tacos and the fried English cod sandwich, and they enjoyed them very much, as well.  Both of them lived in Maine before coming to PGH, and they told me that this was the first really good seafood they'd had in the city thus far--and they've been living here for 3 years!\n\nThis place is only open for lunch, and has a very casual vibe.  We sat by the large front windows, which provided a great opportunity for people watching.  In general, I'm a fan of the ambiance.  One thing that struck me as kind of weird, though, was the ordering and payment system.  Instead of paying when you order at the front counter, as at most fast casual restaurants, you pay after you've finished eating.  This was a bit confusing, and I'm not sure why they do this unless it has to do with tipping for waitservice.  I wouldn't call the waitservice standard, however, because although they bring out your food and clear your plates, you order and pay at the counter, not at the table.  Because of this, it wasn't obvious that a tip was necessary, so I didn't leave one (I didn't even think of it at the time).\n\nOverall, this is a great place, and I'd definitely recommend stopping in if you're a seafood fan next time you're strolling the Strip.  I'll definitely have to return to try the sushi, since it looked very appetizing, as well!
