I will be visiting San Francisco for the first time soon for two days and nights and I want to know what should I eat that will be a true representation of the city. I love Sour Dough Bread so this is basically going to be like a trip to Mecca for me, any suggestions on who has the best? What food or dish should I eat that will give me "San Francisco on a plate" (I'm from Philadelphia so I want to eat the San Francisco food that is analgolous to our cheesesteak). I also love crab so I would like to have dungeness crab out there, any suggestions that aren't a tourist trap? I am on a budget, I'm thinking $15-$30 per entree but I'm open to whatever! Thanks everyone for your help!
