The Rainbow Room occupies the eastern part of 30 Rockefeller Plaza's 65th floor, which occupies a footprint. The central part of the floor features elevator banks, restrooms, a gallery, and a private dining room. The western part houses Bar SixtyFive and an outdoor terrace. The restaurant proper occupies a space: its eastern and western walls are long, while its northern and southern walls are long. Entrance to the Rainbow Room is from the west, and two small staircases from the western wall extended to the northeast and southeast so as to avoid the rotating dance floor. A raised platform at the northwest corner of the room allows a full view of the space. The seats of the Rainbow Room are organized in "tiers". The northern and southern walls, as well as an alcove on the Rainbow Room's east end, offer single-tiered seating, while the northeast and southwest corners contain double-tiered seating. Between the staircases on the restaurant's western side, there is also a platform for bands and a shallow balcony for entertainers. The handrails on the staircases behind the platform contain brass mullions with glass panes between each mullion. There are also stairs and a dumbwaiter behind the platform, which lead to the 64th floor kitchen. False columns on the eastern wall conceal small compartments for operating the platform's floodlights. Private events are also hosted in several banquet rooms on the 64th floor.
