USA Brooklyn Delicatessen is a deli near Central Park and a subway exit that serves pastrami and corned beef sandwiches and pizza. The Reuben sandwich, made with rye bread, pastrami and melted Swiss cheese, and the sausage, egg and cheese sandwich are listed as signature items. Breakfast is served until 11:30 a.m., and milkshakes are finished within 30 seconds of ordering. The shop is small, so when it is crowded diners bump into each other, and the sandwiches are small in portion.
