Ami was surprised at how many Italians there were in San Francisco. North Beach is heavily Italian and there are tons of restaurants. We went to Caffe Trieste, just a block north of our hotel on Broadway several times for capuccino. We bought books at City Lights, had pizza and burgers and seafood. Golden Gate Park on a warm, sunny day is amazing. The botanical gardens there is one of the best I've ever seen, and all open air. The trees! The plants from all over the world! The Japanese Tea Garden! The quaintness!
The prices! We're poor now.
Haight-Ashbury is pretty tourist-ruined and a big disappointment overall, but we did find a great bookstore and Amoeba Music is absolutely wonderful. If I lived in San Francisco, (oh if I lived in San Francisco!) I'd be in there for days.
