Below the lobby is the complex's shopping concourse, connected to the lobby via escalators. The building has a direct entrance to the New York City Subway's 47th–50th Streets–Rockefeller Center station via the concourse. There is also a mezzanine that contains balconies overlooking the lobby. The floors of the mezzanine are black terrazzo, while the walls are made of marble and plaster separated by a bronze molding. Offices from the outer walls open onto the mezzanine balconies. There are staircases from the lobby to both the concourse and mezzanine, located west of the lobby's elevator banks.
