Sadly I had the same experience as the few others below. No revolving bar, no option other than all you can eat. Was told by the waitress that it was 9.95 for the all you can eat sushi. Seemed like plenty of servers and waitresses. Ordered drinks and food, never saw anyone after that. Flagged down servers and they said they'd put in our next order, but we never received it. Then while leaving, not 30 dollars for 3, instead it was almost 70! I complained to the head guy, he said "oh yeah, I know. We had someone call in today." I said "the price isn't right, the girl told us 10 per person." He said "no, it's 20 plus tax".
Do they have the term "bait and switch" in Japan? This was a horrible experience. I can't imagine returning.
