Went here with a Groupon. Go there for the teppanyaki - make sure you reserve a teppanyaki table beforehand as they do get quite busy.
Upon being seated, learned that it was all you can eat. The teppanyaki cook was very enthusiastic and friendly and put on quite a show for us. The seafood teppanyaki was done well. I especially enjoyed the grilled salmon and flounder. Sushi and sashimi were good but nothing special.
Would rate the food as 4 stars and the cook as 4 stars, but some of the waiters need an attitude adjustment. Here is the bad news: the restaurant screens out groupon users. Tried calling once and mentioning the groupon - sorry all booked up. Called again and made a reservation for the same time without mentioning the groupon. However upon finishing our food, the waiter cross referenced our reservation and refused to honour the groupon. It was only after a lot of hassle that we were able to negotiate a partial deal of the groupon. In addition the waiter was very curt when serving and would scowl when we were ordering food - as though we were ordering too much. As other AYCE, food orders were dropped.
All in all, would go back, but only with the groupon and would reserve well in advance to get a teppanyaki table.
Teppanyaki - 4 stars
Chef - 5 stars for attitude
Waiter - 1 star
