We've been going to O-sho for lunch for many years. They have one of the best valued lunch specials in the area! For under $7, you get miso, salad, 2 gyoza, rice, chicken teriyaki, and tempura! For under $7!! Sodas are ""by-the-can"" so you're better off sticking with water or iced tea. Sushi there is good, but not particularly remarkable or inexpensive. Tables tend to be small, so this is not an ideal spot for a large group. Keep it to 4 or fewer and you'll be quite pleased.
Pros: Great lunch special, very tasty food
Cons: Small groups only, very noisy, can get very busy at lunch
