$20.00 for all- you- can- eat, and it's made fresh to order, not buffet style. Quality is pretty good, and you certainly can't go wrong at that price. Green tea comes free with the sushi also.
The only thing is, you have to pay extra for anything you waste. If you leave one or two pieces because you're full, they don't care, but they have that policy to keep people from ordering a huge pile of food and then not eating it.
