Health-conscious fast-food, including Italian hoagies and salads, keeps sub lovers satisfied.. In Short Founded in 1964 in Hoboken, New Jersey, this sandwich joint has grown into a nationwide restaurant chain. The generously sized subs are modeled on the balloon-like shape of a blimp, which also inspired this chain's name. Famed for its Italian bread and sliced meats, the restaurant offers signature sandwiches, including the Durango Roast Beef, the Baja Turkey and Cheese and the Tuscan Ham and Swiss. Look for grilled panini, wraps, soups and a special kid-sized sub.
