I have a friend from the mid west who visited San Fran once and has a totally warped vision of the city. Out of crazy circumstances he only visited the Mission and Tenderloin and is now convinced the entire city either smells like piss or is covered in junkies. I would like to take him to some must try places that will win him over. His budget is not large so the cheaper the better I think. His food tastes are kind of conservative but he is starting to branch out a little. Let me know if you have any ideas for places that could change his mind.
