You guys have never let me down when I asked about Palm Springs, LA, etc. Now I am getting to SF and excited about visiting. Here are the basics I am looking for- a great place for an anniversary dinner (4th) (so far we are thinking Michael Mina); a good tacqueria in the Mission district; a place to eat at the wharf and anything else you can think of- haveto get sourdough and chowder, lots of fish, and, most important to me, a GREAT burrito. Cheap to expensive. Any help is greatly appreciated, including places to avoid b/c of things that may be going on that I don't know about.
