* - The Asian Art Museum is the largest outside of Asia, it's downtown, Civic Center.
* - Golden Gate Park is awesome, both the art and nature museums there rock.
* - It's a much better deal to take the GGT Ferry from the foot of Market Street (the Ferry Building) to Sausalito get off, stroll about and have some lunch or something then take the GGT Ferry back to the Ferry Building then to take one of those Red/White, or Blue/Gold tourists boat trips.
* - The Alcatraz Tour seems touristy, but it's not. Lots of hard uphill walking though. Worth it.
* - Hiking the trail from the GG Bridge to Land's End and the Sutro Baths is totally amazing, easy, and free. Major bus routes are there at both ends of it. No stores on the route though, so bring some water and other provisions. It's about 3-4 miles.
* - Pretty much all the Italian joints in North Beach, and the Mexican places in the Mission are pretty good. Too much competition for bad food to last long.
