The wait time usually isn't too bad, about 15 minutes. We usually need to wait until enough people arrive which want the meal prepared in front of them. The chefs are always entertaining during their prep of the meal.
The food itself is ehh ok, nothing outstanding at least everything I have tried from the performance meal (most of it). Their sushi is really good, a very nice size and fresh.
We mainly go just for the entertainment value.
If you want to be entertained its a winner, if you want to go simply for a meal its average.
