About Upper East Side

Upper East Side (UES) was once known as the Silk Stocking District. As one of New York City’s most affluent neighborhoods, Upper East Side has its fair share of high-end boutiques, fancy restaurants, and art galleries like Salon 94 and Acquavella Galleries. The neighborhood is also a popular location for films and television shows. Some of these shows and movies include I Love Lucy (1951-1957), Gossip Girl (2007-2013) and Confessions of a Shopaholic (2009).

Upper East Side also has a historic district. It is one of the city’s largest districts, which runs from 59th to 78th Streets along Fifth Avenue. After the Civil War, Upper East Side became a thriving middle-class residential neighborhood. And at the start of the 20th century, the neighborhood transformed once more, but with more mansions and townhouses.
