The view from the top of twin peaks is pretty stellar if it is clear. Scoma's is pretty good, I always liked Pacific Cafe out around 30th and Geary, good food and reasonable. They give you a glass of wine while you wait for your table, so maybe not for you. Ghirardelli Square and the Wharf for the touristy thing. Lot of stuff to see in GG Park, you could spend all day checking that out if the weather is nice on Sunday, they close down a lot of the roads. If weather is bad, Exploratorium is indoors. If you do the tour of the Anchor Steam brewery, they used to give you free samples. If driving, remember that sometimes 3 right turns is what you need to do to make a left
The zoo is pretty good, don't get drunk, smoke dope and tease the tigers
