I'm with you JohnJ regarding scoping out places to eat, between connections. There is a pretty good Asian place, that has some great chicken/beef stir fry dishes, inside Terminal 4 (Southwest), whenever I'm changing planes, in PHX. Also, I really like the sandwiches at Potbelly Sandwich works, at MDW. Also, the brisket, is excellent, at Pappas BBQ very good, at IAH terminal E.
