Sushiyama is a little restaurant serving authentic Japanese food--and I do mean little, the space is very narrow, but somehow they manage to fit something like 40 people in there at once. The staff is all Japanese, and the menus on the walls are in Japanese as well. You can dine at a table or a bar. Last time I was there they had greatly expanded their menu. Besides sushi, they have many varieties of udon and soba noodle, as well as tempura, edamame, bento boxes, and many other Japanese favorites. Since their menu expansion, they actually have a lot to offer vegetarians too. Big plus, you can order Japanese soft drinks here too, like Ramune and melon soda. Prices are low as far as Japanese restaurants go, around $8 for an entree. Very highly recommended!
