Alcatraz, Fisherman's Wharf, driving on the Golden Gate Bridge, Golden Gate Park, Chinatown (I visited a fortune cookie factory there), Muir Woods (just north of S.F.), and driving on the crookedest street in America, Lombard Street.

Walk over the Golden Gate Bridge, stroll through china town- there is a fortune cookie factory there which is kinda fun to check out, Hike up to see Lombard street, a night out in the Castro is fun... but personally, i love to just walk around and wander through the different neighbourhoods!- they are so distinct in San Fran!
Try Kitaro Sushi restaurant on Geary Blvd.. Its a student place or take a date there. Its daym cheap, but the sushi is fast and authentic to the taste.
