Some are geographical (the Upper East Side), or ethnically descriptive (Little Italy). Others are acronyms, such as TriBeCa (for "TRIangle BElow CAnal Street") or SoHo ("SOuth of HOuston"), or the far more recent vintages NoLIta ("NOrth of Little ITAly"). and NoMad ("NOrth of MADison Square Park"). Harlem is a name from the Dutch colonial era after Haarlem, a city in the Netherlands. Alphabet City comprises Avenues A, B, C, and D, to which its name refers. Some have simple folkloric names, such as Hell's Kitchen, alongside their more official but lesser used title (in this case, Clinton). Some neighborhoods, such as SoHo, which is mixed use, are known for upscale shopping as well as residential use. Others, such as Greenwich Village, the Lower East Side, Alphabet City and the East Village, have long been associated with the Bohemian subculture. Chelsea is one of several Manhattan neighborhoods with large gay populations and has become a center of both the international art industry and New York's nightlife. Chinatown has the highest concentration of people of Chinese descent outside of Asia. Koreatown is roughly bounded by 6th and Madison Avenues, between 31st and 33rd Streets, where Hangul signage is ubiquitous. Rose Hill features a growing number of Indian restaurants and spice shops along a stretch of Lexington Avenue between 25th and 30th Streets which has become known as Curry Hill.
