I worked on a startup for a month from the SF public library near the Civic Center. The trick is to go up to the 4th floor, where they have some really nice reading rooms with power and free wifi, and pretty nice views of the outside. Good light, too. Just make sure to empty your bladder before coming, because you sure as hell don't want to use the restrooms (I've seen homeless people bathing in the sinks).
