Duffy's Subs adds a unique twist to the fare of Philadelphia by splashing its lengthy subs with creative ingredients and parading them out to patrons at counter seats, an outdoor patio, or via local delivery. Philly cheesesteaks—bundled with either sizzling slices of beef or chicken—silence appetites or overly talkative friends with a choice of cheese, grilled mushrooms, onions, and green peppers. Not content with merely tapping Philly's flavors, staffers also convert other classic dishes into sandwich form to produce specialties such as the ham-omelet and bacon-cheeseburger subs.
