try the city beer store. i found pliny there on my honeymoon. i've been there a few times and they don't always have it on the shelf, but they do always have a fantastic array of beer to choose from.
City Beer Store, 1168 Folsom St # 101, San Francisco, CA 94103-6028
on tap? try toronado on haight street. otherwise, on draft, it's kinda hit or miss. there are a ton of good beer bars in SF, though, so you really can't go wrong.
and really, if you can get to russian river in santa rosa it is well worth it.
cheers, and good luck.
