You’ll feel like you stepped into a bygone era at this highly praised, homey hamburger joint, which has been serving a concise menu of burgers, sandwiches, and three kinds of pie since 1947. (Some of the staffers have been working there for nearly as long.) Patrons line up against the walls and wait for a coveted seat at the counter. It’s an unusual ritual for today’s fast-food fiend, but obeyed by customers secure in the knowledge that once they sit down they will enjoy a distinctive burger, served sans plate, made according to time-honored tradition and delivering super satisfying taste.
