Somebody Help This Poor Girl

This time, it’s personal. I need your help. I’m going to San Francisco this weekend. (This is my first time. I’ve already learned that it’s not cool to say San Fran.) I’m planning on running the Nike Women’s Marathon on Sunday. But I’m going to need some fuel. Where do you all suggest I go for some carbo-loading Saturday night? I posed the question on Twitter, and SFToDo suggested Acquerello, Pasta Pomodoro, or Firenze by Night. But I’m picky and don’t want a chain, nor do I want to spend a lot of money. I really just need a great plate of pasta. Any suggestions?
