The bartenders here are expert mixologists—try the rye, amaro, and ginger beer “In-Laws”—but the everyday whiskey sours are made with fresh juice, too. That’s emblematic of Blackbird’s relaxed but classy scene: The interior, papered with vintage disaster headlines, is artful without being pretentious; the crowd, a blend of straight and gay, is stylish but laid-back; the ambience is lively but (on weekdays) there are enough open couches to sit and enjoy some conversation.
