Avoid the Luigi Stefani pizzeria. Absolutely gross, hard to believe airportpizza can be so much worse than Sbarro's. I imagine Cuck E. Cheese pizza tastes like this.
Potbelly is awesome: great sandwiches on freshly madebread, IBC rootbeer (regular & diet), delicious cookies, and Starbucks coffee....you can't go wrong. Vegetarian choices too.
