Sugar Hill n.
1. [1920s–40s] that area of Harlem otherwise known as Coogan’s Bluff, between Amsterdam and Edgecombe Avenues, between 138th and 155th Streets. As well as the rich, many black intellectuals and artists chose to live in the area, known for its grand apartment houses, once the original white population had moved out during the 1920s; thus Sugar Hiller, a resident of this area [sugar n.1 (1)].
2. [1930s–50s] the brothel and ‘red-light’ area of the black part of any southern town [sugar n.4 (1)].
