I've been here twice for lunch. The service was friendly both times. It was also crowded both times from about 11:30-1pm. First time I got a chicken teriyaki bento box. It was both delicious and affordable.
The second time I got the all-you-can-eat lunch buffet. What a HUGE menu! The taro, pumpkin, and shrimp tempura were all excellent. The unagi, salmon skin, raw salmon, and fish roe were all very good sushi. The other sushi I had was pretty good as well. With such a big menu you're sure to find something you like. Other suggestions: seaweed salad, garlic mushrooms, green tea ice cream.
