Lots and lots of selection for AYCE! Dinner was $24 which is a couple bucks cheaper than most AYCE sushi places in Vegas.
I really enjoyed the sides at Yama Sushi! Loved the tempura, BBQ ribs, agedashi tofu and gyoza. The nigiri sushi was fresh and delicious. Rolls were yummy as well - be careful though since some of them are really heavy and can fill you up quite a bit! My favorite roll was sun of a beach.
Yama gets really busy so be prepared for a long wait. I came on a Friday night and waited a hour during prime dining hours. The service is fairly quick when you do get seated though!
