My husband and I are coming to CA at the end of July for a wedding in Napa, and to "do" the San Francisco area. We're arriving at SFO around noon. Since we're coming in from the East Coast, we will be more than a little hungry. I've heard lots about In-N-Outs, but we don't have them over here. Which one do you recommend on the route from SFO to Napa (and even a recommended route would be great- Mapquest says downtown- that can't be the best way)? Thanks!
