For more than fifty years, this boxy luncheonette has turned out sliced- and chopped-beef sandwiches as good as you’ll ever eat, plus smoked-ham sandwiches and smoked burgers. That’s all, but that’s enough. The brisket, cooked for sixteen to eighteen hours in a well-worn brick pit, is lean and succulent, with a char that crunches slightly. Grill-warmed buns are brushed with a thinner, more red-peppery version of the mild house sauce.
