We have almost three hours to kill, so I guess we'll have time to hit any terminal. Any Philly Cheesesteak that you can recommend, or any other decent chow?

They have your typical food court with Chinese, pizza, and sandwiches.

My favorite place to eat there is in Terminal B...Cibo's. I love the chicken rose. It comes with a salad and bread. It's pricey but good. I think they also have one in Terminal A.

And there is a bar across from the food court that is supposed to be good but I've never been there.

They have a lot of shops to walk thru while you try and kill time. I like Fire and Ice. But not sure if you're inot jewelry.

I agree with the previous poster...most of the offerings are food court garbage. There is a TGI Fridays where you can eat from a menu but they have to have the worst service in America at this location...
The Cibo's is OK and, at the inner end of terminal C (the far end) there is a soup, salad and sandwich place that is pretty good. I can't remember the name of it but it is at the very end of C.
If you want to brave going back thru security, you can also walk over to the attached Marriott for a decent meal

We're coming into Terminal F, are the shops accessible from there? Or does it require a shuttle or tram or something?

I seem to recall you will have to go through security again to get into the connected terminals that include the Food Court, because Terminal F is separate (but walkable). I had a flight out of Terminal F in PHL a few months back and had expected to eat at the food court but once I realized I would have to go through security (assuming they let me in with a Terminal F boarding pass), I didn't want to have to go through the extra hassle, so I just ate at one of the fast food choices in Terminal F. There may be a bar-type of place in F too, I don't remember. If I had three hours, though, perhaps I would brave exiting F to the other terminal, if the lines aren't too long. At the right time of day, there are no security lines at PHL.

figures... looking at cusine suggestions on Fodors in an airport...

I cannot recall the terminal or the name of the place, but, a few years ago, I was in connection heaven somewhere with two for one drinks and the most amazing crab cakes anywhere on the planet (including the ones I make at home, and I'm from Baltimore).
