1300 Fillmore is really good. It's only a few month's old, but has caught on very well and has become one of our favorites.
We really like SOQR, but their tiny space and no reservations policy makes eating there tricky. I think the long waits at SPQR have ended up being a boon to Florio right next door, a solid bistro, but not particularly memorable.

You're just north of Japantown and all the sushi and Japanese food spots there - Kiss, Ino, and Kappa. For special occasions, Kappa has a killer omakase menu if you call in advance to book.
There's the newly re-opened Cafe Majestic with Chron's 2008 Rising Star Chef, Ian Begg.
On Fillmore Street, SPQR and Fresca (Peruvian).
