Sushi quality is okay. When I go there, I usually do not eat the sushi. The flying fish roe was so salty. The octopus was stiff. And everything else was just overly embellished it was essentially not sushi. Something about sushi buffet freaks me out - I can't help but to equate that with cheap sushi and with cheap sushi = cheap fish = higher levels or mercury? The steak (london broil) is pretty flavorless. And the meat texture is too tough. But come to think of it, it is a buffet so I cannot really be too critical. I love their clam soup. That is pretty much the only thing I eat from there. I love the clam stock and the ginger.
I also really like the tapioca in the dessert section. My only suggestion is to leave out the fruits and the taro and perhaps put them separately on the side so people can add as they please. I for example, do not like taro. My sister on the other hand, hates having the melons in there because it dilutes out the coconut flavor the tapioca is supposed to have.
Don't get the kiwi fruit. It is obnoxiously sour and has consistently been. As far as ice cream, they should try to be a bit more diligent about cleaning the water bin that holds the ice cream scoops and the ice cream scoopers themselves. The water is usually murky and the handles are all sticky :-/
The biggest and major complaint I have is the management. I am a student so I get 10% or 15% (I don't remember which) off. I gave the server my student ID and a gift certificate I had. She came back to inform me that she is not allowed to let me use my student discount with my gift certificate. I spoke to the manager and she actually put up a fight about it. It is 110% understandable if I'm using a discount on top of another discount, but no, this was clearly not the case. And no, the manager did not budge. So I was, and still am, absolutely livid about the fact that she was trying to hustle me.
