I am going to be in San Francisco on Sunday August 20th. I like to eat and i like good food, i don't care if it is a street taco for a dollar or a tasting menu for $100 as long as it is good. I have the entire day to myself on Sunday and have never been to SF. I would like to eat and drink my way through the city. My plane doesn't leave till wee hours of monday morning. Please guide me.
