It doesn't matter what time you stop by Potbelly; there's usually a line of hungry 20- and 30-somethings waiting to get their fix (good thing the behind-the-counter staff is so fast). Yes, there's a potbelly stove inside, along with other Old West saloon-type memorabilia, but fans come here for the made-to-order grilled sub sandwiches (that's all they serve). Prepared on homemade rolls stuffed with your choice of turkey, Italian meats, veggies, pizza ingredients, and more, they're warmed in a countertop toaster oven. Even with all the fixin's, each is under $5 (unlike the massive subs found at other spots, Potbelly's "Originals" are more the size of normal sandwiches; however, "Bigs" and "Skinnys" are also available). Though this is the original location, Potbelly has more than 30 others throughout the city, including 190 N. State St. (tel. 312/683-1234) and in the Shops at North Bridge, 520 N. Michigan Ave. (tel. 312/644-1008), both of which are convenient to the Loop and Mag Mile.
