If you've never tried Potbelly's, you must go! They have the best toasted sandwiches that are flavorful and filling. Even the vegetarian, my favorite, fills you up thanks to mushrooms and lots of cheese toasted and then topped with fresh veggies. The milkshakes are great too, and if you want, they will mix frozen yogurt with the normal ice cream if you want a lower-fat milkshake. The cookies and cream flavor comes with mini Oreo cookies on top! Everything is delicious and the staff is usually very helpful.
