With a crust that leavens for 96 hours, flour imported from Italy and a distinctive rectangular shape, this pizza is a cut above what’s available at your local slice joint. But you can’t get a reservation to try it — or even order a pie for takeout.

NYC’s most exclusive, sought-after pies are only available via barter. Hopefuls trying to score a small-batch pie have to sign up online, and if they’re chosen, trade their own offering of food or drink.
