Attaboy, ranked number one on North America's 50 Best Bars list, is an intimate craft cocktail destination on the Lower East Side. Operating without a menu or exterior signage, the bar seats just 28 patrons in a cozy space with low lighting and private booths. Bartenders engage patrons in conversation about their preferences, then craft personalized cocktails using classic techniques. The venue is credited with inventing the Penicillin and Paper Plane cocktails, establishing its significant influence on modern mixology.
