Jimmy Weston's Restaurant & Jazz Club was an American restaurant and jazz club in New York City, located on East 56th Street beginning in 1963, then, seven years later, moved it to 131 East 54th Street. Tommy Furtado was selected as the house musician and maintained that position until the club closed twenty years later. Its owner, Jimmy Weston (James L. Weston; 1922–1997), closed it in 1989. The New York Times obituary for Weston stated "Given the restaurant's high-level clientele, it was inevitable that it served as a backdrop for social history. It was at Weston's that Mr. Sinatra patched up his feud with Liz Smith, and Howard Cosell got the call from Roone Arledge telling him he had been picked for a daring new idea called "Monday Night Football."

The Brook is a private club located at 111 East 54th Street in Manhattan in New York City. It was founded in 1903 by a group of prominent men who belonged to other New York City private clubs, such as the Knickerbocker Club and the Union Club. The name is derived from the Alfred Lord Tennyson poem The Brook, whose lines "For men may come and men may go, but I go on for ever" were consistent with the intention that the club would provide 24-hour service and would never close its doors. In 1992, the City Journal wrote that the name was "supposed to mean that the Club is always open and the conversation flows on forever," but that "neither is strictly true." One version of the club's origin holds that The Brook was formed by two young men who had been expelled from the Union Club for trying to poach an egg on the bald head of another club member.When the club was formed, it was announced that membership was only by private invitation and would be limited to 100 men. New York City residents who were not club members would not be admitted as guests. Membership, however, was not restricted to New York City residents—some original members came from Boston, Chicago, and Philadelphia.In 1954 the membership was 400 men. The club's building, erected in 1925, was designed by the architecture firm of Delano & Aldrich, which also designed the houses of the Union Club, the Knickerbocker, and other exclusive clubs.

The Hoffman Auto Showroom was an automobile dealership at 430 Park Avenue, New York City. Designed by architect Frank Lloyd Wright for notable European importer Max Hoffman in 1954, the glass and steel 3,600-square-foot (330 m2) space was located on the ground floor of an office tower located between East 55th and 56th Streets. It was dominated by a sloping floor capable of displaying up to five automobiles. Hoffman, the son of a Vienna Rolls-Royce dealer, had intended to use it for his Jaguar dealership. However, by its completion he had moved on to Mercedes Benz and a large model of a leaping jaguar had to be sent back to Coventry.In early April 2013, the building's owners, Midwood Investment & Management and Oestreicher Properties, demolished the showroom to make way for a TD Bank branch office.

The Citigroup Center (formerly Citicorp Center and also known by its address, 601 Lexington Avenue) is an office skyscraper in the Midtown Manhattan neighborhood of New York City. Built in 1977 to house the headquarters of Citibank, it is 915 ft (279 m) tall and has 59 floors with 1.3×10^6 sq ft (120,000 m2) of office space. The building was designed by architect Hugh Stubbins, associate architect Emery Roth & Sons, and structural engineer William LeMessurier. 601 Lexington Avenue takes up much of a city block bounded clockwise from west by Lexington Avenue, 54th Street, Third Avenue, and 53rd Street. The building has a 45° angled top with a base on four stilts, as well as a six-story office annex to the east. The tower overhangs St. Peter's Evangelical Lutheran Church at Lexington Avenue and 54th Street, a standalone granite structure designed simultaneously by Stubbins. Also at the base is a sunken plaza, a shopping concourse, and entrances to the church and the New York City Subway's Lexington Avenue/51st Street station. The tower stories are supported by stacked load-bearing braces in the form of inverted chevrons. Upon Citicorp Center's completion, it received mixed reviews from architectural critics, but also several architectural accolades. Land acquisition for what became Citicorp Center commenced in 1968 and took five years. St. Peter's Church sold its plot on the condition that a new church building be constructed below the tower. The design was announced in July 1973 and the structure was completed in October 1977. During the Citicorp Center engineering crisis less than a year after the building's completion, emergency repairs were made after the tower was discovered to be vulnerable to collapse due to wind. The building was acquired by Boston Properties and Citicorp Center was renamed 601 Lexington Avenue in the 2000s. The New York City Landmarks Preservation Commission designated 601 Lexington Avenue as a city landmark in 2016. Over the years, the atrium, plaza, and other public spaces have been renovated.
