This place is great! I would come here for somewhat authentic Japanese fare when I had the funds (lived in a student residence on Chestnut street). The atmosphere, smells and most importantly the food took me back to when I visited Japan. The sushi is great and if you'd like to try an entree i'd go with the rice dishes, the gyu-don never disappointed me.
Staff is always extra sweet. During I recall there were several teeny crabs in a cage by the sushi bar. I was smiling at them and one of the employees asked if I had ever eaten one. He then brought out a little deep fried crab for me to try (fo free! holla!). It was a nice gesture but fried up baby crab isn't really my thing.
