Sushi Zono is a small, inexpensive, neighborhood sushi restaurant, don't expect a fine dining type of experience. Sushi Zono has the standard sushi restaurant fare (nothing special on the menu) but the staff are very friendly. Unfortunately, I didn't think the fish was as fresh as it could have been (i.e. compared to some other sushi restaurants in the area) and fried items like tempura were horrible as you could really taste that the oil isn't changed enough.
Pros: very friendly staff
Cons: below-average sushi, horrible tempura
