Backdoor43 (often stylized as BackDoor43 or Backdoor 43) is widely recognized as one of the world’s smallest cocktail bars—and a true hidden gem of Milan’s exclusive nightlife scene. Tucked away in the vibrant Navigli district, this ultra-intimate speakeasy-style bar measures just about 1.2 square meters (roughly 13 square feet), accommodating a maximum of four guests at a time seated at a tiny counter. It delivers an intensely personal, clandestine experience with impeccably crafted cocktails in a setting that feels like stepping into a secret world.
Founded by mixologists Flavio Angiolillo and Marco Russo, Backdoor43 emphasizes high-quality, creative drinks made with premium ingredients and a focus on bold flavors. The bar’s “Drink-Away” concept also allows for takeaway cocktails of the same exceptional standard, available from early evening onward. Its exclusivity comes from the limited capacity, the need for advance reservations (often weeks ahead, typically via WhatsApp or their booking system), and a low-key, unmarked entrance that adds to the speakeasy allure. It’s earned accolades like ranking in the Top 500 Bars worldwide and praise in guides for its uniqueness, mixology skill, and atmospheric charm.
