I just looked at that, and there is food every night (http://www.sanfranciscoairport.hyatt.com/en/hotel/dining/KnucklesHistoricalSportsBar.html). while it is expensive, how close is food from the hotel, how much are taxis, how much is parking, and other such costs.
I am not saying we should not have food outside of the con, i just would like more info about what is near by.
