"Backbar has long been the cocktail spot in the heart of Union Square. Tucked away in the alley behind Bronwyn, Backbar is all underground vibes, with a hodgepodge of decor like the head of a golden eagle overlooking the bar and murals paying tribute to pop-culture icons from Hayao Mizayaki to Star Wars. Make sure to sit at the bar, where you can watch the bartenders mixing, shaking, and stirring seasonal cocktails in a seamless commotion. Pro tip: While Backbar almost always has a line, you can skip it by reserving a ticket to an event, from an exploration of Chinese baijiu to a nerdy Halloween party." - Nathan Tavares, Valerie Li Stack
