Lower East Side

Wikipedia - "The Lower East Side, (often abbreviated as LES), is a neighborhood in the southeastern part of the New York City borough of Manhattan. It is roughly bounded by Allen Street, East Houston Street, Essex Street, Canal Street, Eldridge Street, East Broadway, and Grand Street. It was traditionally an immigrant, working-class neighborhood. But it has undergone rapid gentrification starting in the mid-2000s, prompting The National Trust for Historic Preservation to place the neighborhood on their list of America's Most Endangered Places."
