Union Hall in Park Slope is a cozy, multi-purpose venue outfitted to resemble a stately library with bookcases, banquettes, and a fireplace. It features two bocce ball courts, outdoor garden seating, and a basement space that often hosts comedians and indie bands. There's something on Union Hall's schedule every night of the week, whether it's an NPR live radio show, bocce tournament, or themed happy hour. The bar's down-to-earth vibe is complemented with craft beer and simple bar food like burgers, empanadas, and house-made soft pretzels. The crowd is mostly made up of local Brooklynites, and though don't have to roll up in tortoise-shell frames and cuffed jeans, you'd certainly be in good company if you did so.
