Which direction are you heading? Where are you staying? It would be easier to direct you if we had that information. I can think of my standby Wawa, which is just a couple of miles south of the airport on Rte. 291 in Essington (very close to some of the cheaper airport motels). Wawa is great for a pit stop and has a pretty good deli/sandwich counter for a 1 AM meal. But if you are going into Philly, there are probably better options.
