Boudin is junk, no local would eat there. there are so many better local bakeries. Gharardelli, Pier 39/Fisherman's Wharf, and Union Square are touristy. There's nothing you can't buy there that you can't find online.

Do bring a jacket so you don't end up surprised by the weather.

Alcatraz and Chinatown and Golden Gate Park are interesting/pretty enough.

Better ideas... Eat some dim sum or a burrito. Rent a car and go to Muir Woods. or kayak and oysters in Pt Reyes. Or wander around Stanford/Cal campus. or drive to Yosemite or Tahoe. or go wine tasting and inner tubing in Guerneville. Or find a concert (jambase, songkick...) or baseball game. or take the ferry to sausalito or angel island. or Exploratorium or MoMA or other museum. or aquarium in Monterey and beach in Carmel. or go to the exploratorium. or try the Church of John Coltrane. or the Church of 8 Wheels. go sailing. lots of world-class dinner options. find random happenings on funcheapsf. etc.

Just don't go to those touristy places, yuk.

Ah, thanks. Note to OP, most of these are outside the city proper. I am from the Vancouver area so the weather there never bothers me ;).
