You could always visit Alcatraz Island... it was an infamous prison not so very long ago and has been used in various movies, such as "The Rock" with Nick Cage and Sean Connery.

One place I always try to get to when I'm in the area, is Fisherman's Wharf. Some amazing seafood and sushi restaurants there!!!
