"Okay, I’ve been holding out on you. There is another species of Brooklyn roast beef that takes the form of a hero sandwich topped with fresh mozzarella and soaked with brown gravy, one that may be acquired at delis or Italian salumerias, a dozen or so of which I know about. In fact, G&S Pork Store is only three blocks west of Brennan and Carr on Avenue U, where for $15, you can get a roast beef sandwich of amazing length that most diners would find impossible to finish. The mozzarella is squeaky fresh, the beef caramelized around the edges, and the roll perfect for its purpose: Consider this a third option." - Robert Sietsema
