Output is one of the few clubs in Brooklyn to hold its own against Manhattan's heavy hitters. The club is armed with a Funktion One, one of the best sound systems in the city, making it powerful against the big guys in more ways than one. You'll find more plaid-clad hipsters than stilleto'd models here, but that doesn't mean you won't have to wait if you show up late. Once inside, the main room bumps with high-quality electronic talent, the adjoining Panther Room offers a more intimate listening experience and the rooftop gives you a place to cool down before heading back in for more.
