Julia Richman High
Julia Richman High School is a defunct comprehensive high school in Manhattan, New York. Built in 1923 and located at East 67th Street and Second Avenue, the building was the only public high school in the Upper East Side of New York. The school is named after Julia Richman, the first woman district superintendent of schools in New York City. For much of the school's history it was a girl's high school; it changed to co-educational in 1967. In 1995, after years of academic decline, the city reorganized the school into six separately functioning small schools within a building renamed as the Julia Richman Education Complex. From WIKI.

Smith & Wollensky
Smith & Wollensky is the name of several high-end American steakhouses, with locations in New York, Philadelphia, Houston, Columbus, Las Vegas, Miami, Chicago, Boston and Washington D.C. The first Smith and Wollensky steakhouse was founded in 1977 by Alan Stillman, best known for creating T.G.I. Friday's, and Ben Benson, who later opened his own steakhouse at 123 West 52nd Street, in a distinctive building on 49th Street & 3rd Avenue (once occupied by Manny Wolf's Steakhouse). Many of the restaurants have a wooden exterior with its trademark green and white colors. The individual Smith and Wollensky restaurants operate using slightly varied menus. In 1997, Ruth Reichl, then-restaurant reviewer for the New York Times, called Smith & Wollensky "A steakhouse to end all arguments." From WIKI.
