I really enjoy this place. It can be whatever you want it to be.
I've been there and had nothing but tofu, salad, edamame, and sushi. And I've been there other times and got my fill of the standard heart attack items as well. It's a $10 buffet so don't expect the world when it comes to flavor, but I've tried most of the dishes and they're passable. I generally don't go to buffets since I like quality over quantity but this one is the exception, especially since I can get as much sushi and tofu as I want.
