n.a large sandwich made of a long crusty roll split lengthwise and filled with meats and cheese (and tomato and onion and lettuce and condiments); different names are used in different sections of the United States
The chicken cutlet sandwiches are fine enough, but they do not hold a candle to the delicious roast pork that fills their hoagies (all named for streets in Philly): the Pattinson Avenue with broccoli rabe and provolone is a house favourite.
