The northern, southern, and western ends of the slab slightly overhang the plaza and are supported by bronze-clad columns at their perimeters, which form an arcade in front of the entrance. The arcade's ceiling contains recessed light fixtures within a ceramic tile surface. The first-story walls behind the arcade contain full-height glass panes. Above the arcade on the western side of the building is a marquee made of Muntz metal, with recessed lighting. The bases of the wings on 52nd and 53rd Streets, beneath the first story, are clad in granite and contain entrances to the restaurant and bar spaces inside. The eastern portions of the 52nd and 53rd Street wings contain garage doors, while the eastern wall of the 53rd Street wing is faced in brick. The eastern section of the 52nd Street wing has an entrance that leads to the Pool and Grill restaurants while bypassing the main lobby. A similar entrance exists on the 53rd Street wing to the Brasserie restaurant.
