This is probably some of the all around freshest fish you'll ever get in SF. If you want a more traditional Japanese sushi experience, this is it. If you like rolls, you probably won't enjoy this place. Now on to the bad: service can be hit or miss and can come with a bit of an attitude. Prices are high, however, for the quality, I don't think the prices are totally out there. All in all, a great meal. If you can ignore spotty service, this is worth the visit.
Oh, and if you're a fan of Anthony Bourdain No Reservations, he ate here on the San Francisco episode.
