I came here back when Yelp had Naka at 4.5 stars and I must say that I was extremely disappointed. The nigiri had too much rice and the rolls weren't that great. Not to mention there was only one server/waiter taking care of all the tables. Since I don't want to be a total downer I will say that the quality of fish wasn't bad.
There are many better ayce sushi places in Vegas, don't waste your time and money coming here!
