The penthouse was home to the Restaurant Club Lounge Altitude 737 restaurant and nightclub, that opened onto a rooftop terrace. The club, which was named for its elevation in feet from sea level, was one of the most famous in the city, and featured one of the most unusual dance floors, which twisted and turned around, and spanned two floors. It later became home to the 360 Observatory, which suspended its operations on 13 March 2020 and announced permanent closure on 3 May 2020.
