in San Francisco. Golden Gate Park is terrific, try to see the rose garden and the Japanese Tea Garden. As to food, there are at least 2 types of restaurants San Francisco is known for, seafood places near Fisherman's Wharf and Italian places in North Beach. For the former I still like Tarantino's, especially if they have sand dabs, a local delicacy, but Scoma's is also excellent. In North Beach, the North Beach Restaurant is very good, but if you want to go top scale, Fior d'Italia on Mason St. is superb (but not cheap). Another favorite with tourists are the 'walkaway cocktails' at Fisherman's Wharf, little cups of crab, baby shrmip or a combo with some crackers & cocktail sauce that you walk around with. Also, don't miss Chinatown, with several really excellent Chinese restaurants. Finally, there's the Buena Vista Cafe at Maritime Park, which is known for introducing Irish Coffee to the US. They also have quite good food, especially breakfasts, and a great location with a view. And the Ferry Building Marketplace on the Embarcadero at Market is also a great experience.
Enjoy your visit, it's one of our great cities!
