The island of Manhattan is broken up into 3 main areas – Uptown, Midtown, & Downtown – each with many different smaller neighborhoods. Uptown Manhattan refers to the area above 59th Street. Downtown Manhattan refers to the area below 14th Street. Midtown Manhattan refers to the area between 34th Street and 59th Street. The island is also cut down the middle, with the West Side referring to the area west of Fifth Avenue; East Side refers to the area east of Fifth Avenue.
Manhattan's many neighborhoods are not named according to any particular convention. Some are geographical (the Upper East Side), or ethnically descriptive (Chinatown). Others are acronyms, such as TriBeCa (for "TRIangle BElow CAnal Street"), SoHo ("SOuth of HOuston"), or NoLIta ("NOrth of Little ITaly"). Alphabet City comprises Avenues A, B, C and D, to which its name refers.
Central Park splits the Upper East and Upper West Side. The Upper East Side houses many of the city museums. Above the park is Harlem and the Bronx. Midtown covers the area from Central Park South down to about 34th street. The Theater District is an area within Midtown that hosts the majority of the Broadway entertainment venues. Below Midtown is the Flatiron and Gramercy park district, areas nearby Union Square where the wedding reception will be held. To the west are Chelsea and the Meatpacking district.
Below the Flatiron District there are many ethnically diverse and trendy neighborhoods, including Greenwich Village, the East Village, SoHo, the Lower East Side, Little Italy, Chinatown, and Tribeca. Even further south is Lower Manhattan, which consists of the Wall Street Financial District, South Street Seaport, & Battery Park.
