Weighing in at slightly less than half a pound, Levain's could-be-meals cookies are big, but you'll still wish you had just one more bite after you've finished. The chocolate-chip walnut is divine but the dark-chocolate chocolate chip comes in at a close second, with the brioches not too far behind. All of Levain's treats are either always freshly baked or somehow scientifically engineered to maintain that warm and gooey just-left-the-oven center. The Upper West Side and Harlem locations are roughly 80 percent kitchen and 20 percent counter—this is a grab-and-go spot. And there will likely be lines, but don't confuse them with the queues for some of the city's other infamous treats as you'll be sandwiched between loyal local regulars as you wait.
