The crowds at Eataly haven't melted away since its opening nearly a year ago, and now comes another reason to elbow your way in: the rooftop beer garden, Birreria, which debuted in time for summer. The retractable roof makes it a year-round event, but when it's open to the sky, there are magnificent views of the Flatiron and Empire State buildings. Line up at the elevator near the housewares department and be aware that it can be a long wait, especially at sunset; no reservations are taken for parties under six. The garden holds 150 and serves an extensive menu of house-made sausages and pork shoulder. Something lighter? Try a wild arugula salad or chicken thighs with almond-olive pesto. But what are you really here for? Yes, drinks. Nine wines and 10 beers on tap are supplemented by three cask-conditioned ales brewed on the premises.
