San Francisco's got much more than the "Bridge" and Fisherman's Wharf. Yeah We Be Knives is there with a great selection, but prices are never discounted. Still for knife nuts, it is a destination stop.
Golden Gate Park has a couple of great museums, the DeYoung and the newly refurbished and beautiful Academy of Sciences. Once away from the 'Wharf, the Embarcadero wraps around the eastern side of the city facing Oakland, and is a great walk.
For shopping, go to the Nordstrom center on Market Street. It's got one of the highest open atrium ceiling anywhere around with some really good restaurants, and one of the best is Nordstrom's own cafe.
For another nice walk and cheap entertainment, Grant Street, which is in the heart of Chinatown, offers a lot to see. Sure there are the typical tourist shops, but get off the main street and you'll see a little of what things looked like 100 years ago.
For more sight-seeing, take the famous cable car line up California Street to the "Top of the Mark' and while there enjoy looking at the turn of the 19th century's railroad baron's mansion and Grace Cathedral with their famous labrynth just outside.
There you go, hope that helps!
