I'm flying through PHL airport and have a two-hour layover both ways -- one at breakfast time and one for lunch. I will probably be in Terminal F, so I should probably stick to concourses B to E.
Anything great? Tasty, healthy and Asian are preferred for lunch; anything above fast-food mediocre for breakfast.
(For guidance, I am always very happy to fly through O'Hare and go to Wolfgang Puck Express for their tasty Asian coleslaw w/ chicken, greens & sesame seeds.)
