Coupla decent choices -- Shapiro's Deli by B14 has outstanding Reuben and Corned Beef sandwiches. Worth the walk. Highly recommended. 96th Street Steakburgers by A10 are decent. Giorgio's in the main terminal has good hand-tossed pizzas and calzones, but you have to go outside security for it. Green Leaf's & Bananas by A11 has good salads.
