Gramercy Flatiron actually constitutes at least three neighborhoods in Manhattan, situated between 14th and 34th Streets, east of Sixth Avenue. The western part of this area, to the west of Madison Square Park is the Flatiron. Gramercy can be thought of as the southeastern part of the area, centering around Gramercy Park. Murray Hill is the northeastern part of the area, including a sub-neighborhood comprising approximately 26th-29th Sts. on and around Lexington Av. And the central street of Koreatown is 32nd St. between Broadway and 5th Av.Union Square was completely revitalized in the 1990s and is now one of the city's premier shopping, dining and entertainment districts. The loosely-defined "Flatiron District" extends east from 6th Avenue and north of Union Square, centering on the famed Flatiron Building on 23rd Street. Tranquil, exclusive Gramercy Park is open only to immediate area residents, though the old brownstones surrounding the park and on Irving Place are some of Manhattan's most attractive streetscapes. Toward the north is Kips Bay, an affluent residential neighborhood, and, in the low 30s between 5th and 6th Avenues near Herald Square, an emerging Little Korea of BBQ restaurants and Asian markets.
