Both of my favourite sushi restaurants in SF are in the Inner Sunset. Ebisu, on 9th Ave between Irving and Lincoln (www.ebisusushi.com) has fantastic rolls (love the 49er and the QP rolls) & super-fresh fish. Ask for the live scallops - you get scallops nigiri-style, with the leftover bits tempura-ed and all served with a yummy (maybe ponzu?) heated sauce on a scallop shell. There's usually a wait, and they don't take reservations - you just show up, put your name on the list and wait to be called. They also turn tables over pretty quickly there - not a place for lingering, just eating good sushi.

The other option is Koo (http://www.sushikoo.com/index.html), on Irving around 6th Ave, I think. Much nicer ambience, better for a date. The rolls are great, and their apps are amazing. The marinated artichoke is so good, with a mayo sauce that I keep trying to recreate at home... and the Spoonful of Happiness is amazing - quail egg, whitefish, uni... wow.

I moved away from SF 2 years ago... you might be able to tell that I miss the sushi desperately :)
