I am a big fan of "The Real food Company" near gates C34-42. It looks like you will depart from B, so you may not be able to make it. If you can I would.
The Real Food Company
Real Food offers 8 marche-style serving stations including gourmet salads, sandwiches, Texas BBQ, oven-baked pizzas, sushi, down home cookin, Tex-Mex, pastas, and bakery in a theater-style setting.
