Go anywhere that's only accessible from the G or M train
We're looking at you Analog and Bossa Nova. Park Slope, Bed-Stuy, Bushwick and Caroll Gardens are all amazing places to wander and get a drink in. But you'll want to limit yourself to early revelry if you don't want to spend hours waiting on a cold platform. Seriously, these subway lines just disappear after 10 pm.
