Williamsburg’s first food hall offers a collection of legendary and emerging vendors under one year-round roof. For a crisp-edged square of Di Fara’s Sicilian pizza and a good burger from Corner Bistro, one used to have to go to the original—and only—source. Not anymore. For something more unusual, try dry-aged beef dumplings from the East Wind Snack Shop counter and sweet little Mexican ice cream cones from La Newyorkina. The 15,000 square-foot space has an industrial vibe and abundant seating.
