East Village dive bar the Double Down Saloon (14 Avenue A) offers patrons two things—alcohol and porn. The dive provides all types of adult entertainment: classic porn, porn with plots, animated porn, and more. You name it, and they most likely have what you're looking for. In addition, they have the best kind of porn—the free kind.
The thing is, porn at the Double Down is nothing. Roger Clark's been talking about it. But the suit-and-ties at Gothamist must've just got wind of it, as they recently published an "exposé" about the years-old phenomenon.
Glad they got initiated.
