I'm going out for my b-day tomorrow and was wondering if anyone had any thoughts about good Sushi places in SF. I've only found one really good sushi place (Moki's in Bernal Heights) but I eat there all the time, and was hoping to find something new. I don't care that much about creativity- freshness is what counts for me. And since we don't drive, I would prefer someplace in the Mission/Noe Valley/Castro/Market area if possible. Thanks.
