Lever House is a glass-box skyscraper at 390 Park Avenue in the Midtown Manhattan neighborhood of New York City. The building was designed in the International Style by Gordon Bunshaft and Natalie de Blois of Skidmore, Owings & Merrill (SOM) as the headquarters of soap company Lever Brothers, a subsidiary of Unilever. Constructed from 1950 to 1952, it was the second curtain wall skyscraper in New York City after the United Nations Secretariat Building. The 307-foot-tall (94 m) building contains 21 office stories topped by a triple-height mechanical section. The ground story contains a courtyard and public space, while the second story overhangs the plaza on a set of columns. The remaining stories are designed as a slab occupying the northern one-quarter of the site. The slab design was chosen to conform with the city's 1916 Zoning Resolution while avoiding the need for setbacks, which had been included in previous skyscrapers built under the ordinance. Lever House contains about 260,000 square feet (24,000 m2) of interior space, much less than in comparable office buildings. The construction of Lever House changed Park Avenue in Midtown from an avenue with masonry apartment buildings to one with International-style office buildings. The building's design was also influential internationally, being copied by several other structures around the world. Although Lever House was intended solely for Lever Brothers' use, its small size resulted in proposals to redevelop the site with a larger skyscraper. Following one such proposal, the building was designated a New York City Landmark in 1982 and was added to the National Register of Historic Places in 1983. Unilever moved most of its offices out of Lever House in 1997 and it was subsequently renovated by Aby Rosen's RFR Realty. Following the renovation, Lever House has been used as a standard office building with multiple tenants.

19 East 54th Street, originally the Minnie E. Young House, is a commercial building in the Midtown Manhattan neighborhood of New York City. It is along 54th Street's northern sidewalk between Madison Avenue and Fifth Avenue. The building was designed by Philip Hiss and H. Hobart Weekes of the firm Hiss and Weekes. It was constructed between 1899 and 1900 as a private residence for Minnie Edith Arents Young. The house was designed as a palazzo in the Italian Renaissance Revival style. The 54th Street facade was designed as a four-story structure with a rusticated first story and decorated windows on the upper stories. Because 19 East 54th Street was wider than other houses in the area, the architectural details were designed to be more imposing. The penthouse at the fifth and sixth stories is recessed from the street. The interior was ornately outfitted with a coffered ceiling, a stained-glass conservatory, and staircases with oak paneling. Young commissioned the house after her uncle Lewis Ginter, the founder of the American Tobacco Company, died in 1897 and left her a large bequest. Young leased the home to "Lucille" Lady Duff Gordon in 1920. The house was subsequently occupied by antiques trader Arthur S. Vernay from 1925 to 1943, then by the English-Speaking Union until 1956. Hairdresser Mr. Kenneth operated a salon in the building from 1963 until 1990, when the house's interior was severely damaged by fire. The building was then renovated and has served as Bank Audi's U.S. headquarters since 1993. The New York City Landmarks Preservation Commission designated 19 East 54th Street as an official landmark in 2016.

Le Pavillon was a New York City restaurant that defined French food in the United States from 1941 to 1966. The restaurant started as the Le Restaurant du Pavillon de France at the 1939 New York World's Fair run by Henri Soulé (1904–1966). When World War II began, Soulé and the Pavillon chef Pierre Franey stayed in the United States as war refugees. The restaurant formally opened on October 15, 1941, at 5 East 55th Street on Fifth Avenue, across the street from the St. Regis New York. In 1957, Le Pavillon moved to the Ritz Tower on Park Avenue and 57th Street. Soulé died in 1966, and Le Pavillon closed in 1971.In his autobiography, Jacques Pépin describes how he was first employed at Le Pavilion after emigrating to the US in 1959. He found that Franey and the rest of the staff were underpaid and treated poorly by Soulé, who insisted that he was barely making ends meet, even though he would offer complimentary meals and wine to a large number of celebrity guests. When Pépin and others organized a protest, he found himself physically threatened by organized-crime goons. However, there was soon an exodus of the staff (Franey and Pépin moved to Howard Johnson's) and the restaurant never recovered. Soulé's other faux pas was allowing paparazzi to disturb the Kennedy family (who were regular customers) and their staffers during John F. Kennedy's presidential campaign: when the Kennedy team, which was dining at the restaurant, asked the paparazzi to leave, Soulé insisted that only he had the right, as owner, to determine who entered and left the restaurant, and stated that, even before the election, "the Kennedys already think they are running the country." (Pépin was offered the job of White House chef after the election, but declined.) Daniel Boulud opened a restaurant with the same name in 2021, in homage to Soulé's restaurant.
