The Otis elevators are spanned by a series of neo-deco light bands extending wall to wall. The lobby extends completely through the block, with a giant entrance hall at Monroe Street and a 16-story full-height atrium in the link between the AT&T and USG towers (also designed by Smith) as both towers share a common appearance.[1] The building boasts two public lobbies and a mezzanine-level lobby.[2] The lobbies are among the most lavish in Chicago, and they are all decorated with patterned marble floors and walls, bronze, gold-leaf oak trim, and stylized lighting fixtures.[2][5]
