Sumidas is tucked away on Folsom, away from the downtown shi-shi and well worth the detour! Their new space on the upper floor is very comfortable and well appointed. Their sushi has been fresh with a broad variety of Nigiri sushi - with specialty types on occasion. Both lunch and dinner menus include a variety of cuisines to please your non-sushi eating friends. And the mango sweet rice dessert is awesome!
Pros: great sushi & tempora, quiet
Cons: tables a bit close together - sometimes a communal feeling which is not necessarily a minus.
