Restaurants today have most dietary limitations (real or imagined) and preferences covered. Nut allergies? Covered. Does gluten give you the bloat? Covered. Vegetarian or vegan? Don’t get me started. But if overexposure to burgers has left you bored with them or, worse yet, suffering from burger intolerance, head to Potbelly’s. You can get a lot of great sandwiches, soups, salads and desserts at Potbelly’s. What you can’t get is a sad, smashed hamburger that has been drained of all flavor and desirability.
