There's no reason to harsh on the Philly F concourse. Jet Rock Cafe has really good food made fresh to order and they have those hot/skank waitresses. You can buy a giant, tastey pretzel from the pretzel stand for $1, throw it in their microwave for 30 seconds and it's a nice snack for cheap. The Asian Chao is very fast, on a quick turn you can run in and grab some burbon chicken and be back in the cockpit in five minutes. There are also three places to by coffee on F concourse. If you don't like F concourse take the bus over to the main terminal. They have some of the best airport food in the country; Asian Sky and Sibo.
If you go to Jet Rock and you don't act like a tool, you get decent service. Have you ever watched how hard that short order chef at Jet Rock works? That guy would probably kill to fly a jet for $22,000 a year.
