One of the best sandwich places I've ever been to. If you're hungry be sure to go with the larger sandwich option, it's not that big at all. The addition of avocados is a must with the Grilled Chicken and Cheddar sandwich. The peppers add a nice zesty taste to the sandwich as well.
Being from the west coast haven't ever come across Potbelly but if I ever travel east again it'll be a must-eat spot.
