Very very good sushi consider it is an "all you can eat" spot. I find the quality of fish is usually sub par when AYCE is offered, but Yama sushi fish was fresh. This could possibly be because of how busy this tiny spot gets. Service was decent even during full house and they did not hesitate to keep bringing my guest and I our tuna sushi even though we were ordering 10 orders at a time. One star was lost because of how tight quarters the tables are and everything does tend to feel rushed. Be prepared to wait for your table even on a weekday.
