We went to the Fish Tank restaurant for supper last night. It had traditional Japanese seating: a low table on a raised platform with cushions to sit on. As an American (and a tall one at that), I found it rather cramped, and almost got claustrophobic one time when I had trouble shifting positions.
The food was good though. We ordered meat and other food grilled on spits, such as chicken, mushrooms wrapped in bacon, asparagus wrapped in bacon, fried battered shrimp, fried battered octopus, fried rice, and noodles. They brought the food on individual plates, and then everyone got what they wanted.
