If you are looking for consistent quality, this place is not for you.
We go lots for it's all-you-can-eat, I'm there mostly for the salmon sashimi. Nigiri sushi is not quite worth it as they pack lots of rice in it. I would recommend going on friday nights, after the rush (at around 7-8pm), then they have good sashimi (probably because they buy lots of fresh fish for friday nights)
The things that I like to order when we are there are:
Salmon & Tuna sashimi
Smoke salmon salad
Teriyaki steak & chicken
Deep fried calamari
I don't really order the rest that much as I don't want to fill myself up with rice!
BTW, the tempera is aweful. Don't order.
