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 Seagram Building is a skyscraper at 375 Park Avenue, between 52nd and 53rd Streets, in the Midtown Manhattan neighborhood of New York City. Designed by Ludwig Mies van der Rohe, Philip Johnson, Ely Jacques Kahn, and Robert Allan Jacobs, the building measures 515 feet (157 m) tall with 38 stories and a public plaza. The International Style building, completed in 1958, initially served as the headquarters of the Seagram Company, a Canadian distiller. Phyllis Lambert, daughter of Seagram CEO Samuel Bronfman, heavily influenced the Seagram Building's design, an example of the functionalist aesthetic and a prominent instance of corporate modern architecture. A glass curtain wall with vertical mullions of bronze and horizontal spandrels made of Muntz metal form the building's exterior. The pink granite plaza facing Park Avenue contains two fountains. Behind the plaza is a tall elevator lobby with a similar design to the plaza. The lowest stories originally contained the Four Seasons and Brasserie restaurants, which were replaced respectively by the Grill and Pool restaurant and the Lobster Club. The upper stories contain office spaces of modular construction. Seagram revealed plans for the building in July 1954, when it announced construction of its headquarters on the up-and-coming commercial strip of Park Avenue. After Lambert objected to Pereira & Luckman's original design, Mies was selected as the architect that November. The building's construction began in late 1955 and finished in 1958, although the official certificate of occupancy was not granted until 1959. The Teachers Insurance and Annuity Association of America purchased the building in 1979, and it remained Seagram's headquarters until 2001. Since 2000, Aby Rosen's RFR Holding LLC has owned the Seagram Building. Upon opening, the Seagram Building was widely praised for its architecture. Described in The New York Times as one of "New York's most copied buildings", the Seagram Building has inspired the designs of other structures around the world. Within New York City, the Seagram Building helped influence the 1961 Zoning Resolution, a zoning ordinance that allowed developers to construct additional floor area in exchange for including plazas outside their buildings. In 1989, the New York City Landmarks Preservation Commission designated the Seagram Building's exterior, lobby, and The Four Seasons Restaurant as official city landmarks. The building was added to the National Register of Historic Places in 2006.

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.

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."
