Like its San Francisco incarnations, this eatery is a beacon of Day-Glo retro cool. Jet-lagged passengers line up as classic-rock tunes play out of the in-ceiling speakers, placing orders for all-beef hot dogs, Niman Ranch hamburgers and grilled free-range chicken sandwiches. Thick fries are served hot with every burger at no additional charge. Stave off those airline-food blues with a thick, creamy milk shake.
