While in San Francisco we chose to do ourt own thing and took one the sightseeing tours from Fisherman's Wharf which hit all the usual spots in San Francisco over a two hour period, afterwards we took a trolley to the Fisherman's Terminal building and walked around to check out all the shops and had lunch at Hog Island Oyster bar. It can be a little pricey, but has a great sampler selection of oysters.
