I think the prices at the "local" places at SFO are roughly a factor of two of the cost at their regular locations. Also, a lot of the good stuff at the regular restaurants isn't available at the airport, possibly because they aren't allowed good knives to cut up fresh ingredients?

I was thinking of suggesting Max's in Burlingame (take the Hyatt shuttle, walk across the street) but Max's web page, which might be out of date, says that location doesn't open until 9 am.
