I stopped writing reviews on Yelp because it was too time consuming, but after eating at this restaurant, I can't help but tell the world about our experience, one that I hope will make other people wary of coming here.\n\nWe arrived at Osaka on a typical Saturday afternoon (1pm-ish) and was shown a table in the back room (where the tables were larger).  As we walked past the first room upon entering, I noticed that it was fairly empty but it didn't struck me as odd since there are so many restaurants to choose from in Las Vegas.\n\nWe sat down and were given multiple menus, each one with something different in it.  I guess this could be a good thing since I like having lots of choices.  We ordered our drinks (hot green tea and iced green tea) and browsed the menus for omakase, which we heard from someone (ahem) that it is worth coming here for.\n\nAfter everyone in our party arrived (there were 5 of us), we asked the waitress about their omakase and she completely hesitated. I thought that was strange considering this should be a simple question.  She said she'll be right back, so we sat there, thinking maybe she's just new or something.  But even so... o_O.\n\nShe came back and in broken English asked us if we wanted sashimi or sushi, and we said a little of both.  She then proceeded to say that it's $100 for all four people that wanted it, and I confirmed if it was $100 per person, or if it was $100 for all four people because that makes a HUGE difference.  She said $100 for four people, so we agreed.\n\nAfter ordering the \"omakase\" - I realized that she must have ordered us the plate of normal sashimi/sushi that was on the menu.  I remember seeing $50 for 2 people for something, so with 4 people, she just doubled it.  I thought sure... why not.  We were going to try their assortment of rolls, but given that the omakase is supposed to be good, I decided to give it a try.\n\nThe first plate of sashimi came out looking decent.  I'm not too familiar with the names and the translation for the type of fish, so I'm just going to say that I tried just about everything on the menu and only a couple items tasted okay.  There were quite a few nasty bites in between, including one in which I had to spit out.  Now, I'm not a sushi snob at all, but when I have to do that, it means it's NOT good.  My companions agreed, and another person had to go thru that ritual later on in the meal as well (said one of the fish tasted grainy too).  Fortunately, our napkins were right in front of us.  =)\n\nAs an additional note, we received 2 additional plates of sushi rolls which were supposed to be part of the omakase deal.  We thought it was just so-so as well... perhaps even bad.\n\nAt the end of the meal, we noticed the $100 + $70 on top of our other charges.  We asked about the $70 and they said it was for the 2 plates of sushi rolls that accompanied our sashimi omakase plate. Needless to say, that $70 was a surprise because we were told  it was $100 for four people.  If they told us they were going to bring additional sushi plates for $35 each, I think we would've either said no, or ordered or own rolls.  Ugh.  I hate when mess-ups like this happen.\n\nWe told our waitress about the issue and she left to talk to the owner/mgr.  The owner/mgr. came by quite awhile later to ask us what the issue was.  We explained clearly about the unexpected charge and the miscommunication but he wouldn't budge.  In fact, he brought up how good of a quality the fish were, and given that, this is still a good deal.  The whole time, I kept thinking if I should tell the truth about the quality of his fish, but I kept my mouth shut in case he was going to give us a break.\n\nI suppose we all could've said something because at the end, nothing happened out of the negotiation.  He wouldn't even take the charge of one $35 plate of sushi off, so we paid, left, and vowed never to come back.  \n\nI've had a lot of sushi before, but I would rank this as the worst sushi AND experience ever.  There are a ton of other great sushi restaurants in Vegas, so look it up on Yelp and go there.  You will not regret it.
