The entrance connects to a lobby with restrooms to the east, a coat check to the west, and the dining room to the south. The main dining room is slightly above the 53rd Street lobby, reached by a set of stairs. The lobby is on the north wall of the main dining room, while kitchens and waiters' stations are on the south wall. A second dining room is reached through a doorway at the center of the west wall. A door on the south wall leads to a fire stair to the lobby. The Lobster Club's main dining room has brightly colored furniture and upholstery; 150 drip-painted concrete floor tiles by Laura Bergman; and three bronze-partitioned booths on the south wall. There is a bar on the eastern side of the dining room. The second dining room is a private dining room with white partition walls, red terrazzo flooring, and metal sculptures.
