The 65th floor of the building is an event room and restaurant named the Rainbow Room, previously run by the Cipriani family. Opened in 1934, it was the first restaurant to be located in a high-rise building and remained the highest elevated restaurant in the United States for decades. Suffering from a decline in business following the financial crisis of 2007–08, the restaurant closed in 2009. In 2012, it was declared a New York City landmark by the Landmarks Preservation Commission.
