Though this East Village bar’s name (short for Please Don't Tell) reflects its speakeasy vibe, it's far from secret. In fact, PDT, which was opened by award-winning cocktail guru Jim Meehan in 2007, helped usher in the city's craft cocktail revolution, paving the way for places like Death & Co. and Pouring Ribbons. The bar is only accessible through the phone booth at the back of Crif Dogs, a St. Mark's restaurant serving hot dogs. The small, retro-inspired space is dimly lit and has exposed brick walls adorned with an assortment of taxidermied animals. Patrons sip on traditional cocktails, such as the Old Fashioned, made with bacon-flavored bourbon. The bar offers a small menu, and customers are permitted to order food from the Crif Dogs kitchen. That is, if they can get in: PDT is notoriously impossible to get into—call ahead for reservations.
