We just got back a week ago. We stayed in the Union Square area. Some of the highlights were: walking down to the Ferry Building, taking a bus out to Golden Gate Park and walking around the Japanese Tea Garden, (we would have liked to have seen the De Young, but we got there too late in the afternoon to have done it justice), took the trolley to Fisherman's Wharf, walked around and found our way to Buena Vista and had an Irish coffee.
