Backdoor 43

Backdoor 43 is one of Milan's most intimate cocktail experiences, claiming the distinction of the world's smallest bar at just 43 square feet in the Navigli district. Designed to accommodate only three guests at a time, this neo-Victorian hideaway features rows of carefully curated whiskey bottles embedded in its wood-panelled walls. Entry requires advance reservation and a minimum one-week booking window. Inside, a skilled bartender crafts custom cocktails from a rotating menu, with patrons enjoying complete control over the ambiance, music, lighting, and glassware for their exclusive 90-minute visit or takeaway drinks from a discreet window service.
