I have sat in the dining room as well as the hibachi grill on several occasions at this restaurant. I've never had a bad experience while dining at the grill. The food has always been superb and the chefs are very entertaining!
The dining room experience is less than satisfactory, however. Each time I've been there for sushi, I've had to wait 30+ minutes for my meal (the wait has always been acknowledged by the staff...last time each waiting table was given complimentary edamame). Not enough sushi chefs (only 1 person was working on each occasion) and/or wait staff.
I'd love to give this restaurant a higher rating, but until I see stellar service throughout the establishment, I have to go with ***.
