The Masquerade Chelsea Halloween Party | Underground Masquerade | NYC Nightlife 176 8th Avenue, New York, NY 10011 Time: 9 PM – Late Tagline: Behind every mask lies another identity. Hidden beneath the streets of Manhattan, The Masquerade invites you into an intimate world of mystery, temptation, and anonymity. Descend beneath the French restaurant and enter a candlelit, Parisian-inspired hideaway where ornate masks, cocktails, costumes, and late-night music set the stage for a Halloween affair built around the allure of the unknown. Inspired by the decadence of European masquerade balls and the secrecy of Paris after dark, The Masquerade trades the traditional haunted house for something more seductive, sophisticated, and mysterious. No mask? No problem. We'll have yours waiting. For those searching for an underground Halloween party in NYC, a masquerade party in Manhattan, or an intimate alternative to the city's massive Halloween events, step behind the mask and become whoever you want for the night.
