I am visiting San Francisco for a week this summer with my boyfriend. We are looking for great places to eat that aren't expensive. We are staying in Oakland, but plan to be in San Francisco frequently, as well as going to Napa and Muir Woods. We will have a car, and are fairly adventurous eaters. Any suggestions for nightlife would be great too, especially places with live music. We want to have an authentic San Francisco experience. Thanks!
