Although the subway is largely a pretty crappy place to be, it does have redeeming qualities: 1) it's a marvel of modern logistics, shuttling you from place to place daily, and 2) it allows you to aggressively drink without ever having to set foot in a car.
So that you can do the latter more awesomely, we present the first-ever Brooklyn Subway Bar Map (click here to enlarge!), wherein we list the best bar within a five-minute walk of basically every stop, and skip any without something good. By no means are you required to turn this into a bar crawl, but we're not the boss of you, so do what you want.
Oh, and obviously we already did one of these for Manhattan.
