I'll be visiting San Francisco for the first time in October--staying for nine days. For four of those days, I'll be attending a conference while my spouse goes bicycling, gawping at nature, etc. We are staying at the harbor Court; the conference is at the Hyatt Regency. I'm looking for ideas on where to have lunch for 4 days--Wednesday through Saturday--within walking distance of the Hyatt, and that I can get to and eat in an hour. Also dinner places--we get an hour to an hour and a half for dinner, from 5:50 to 6:30 or 7:00. I'd like to find place under $30., that a solo woman would feel comfortable in, and might have vegetarian options. A non-related food question, is it safe to walk back to the Harbor Court at night, around 9-11pm? Thanks a bunch!
