Smorgasburg better sleep with one eye open. At 60,000 square feet, this Downtown Brooklyn operation is slated to be one of the largest food halls in the country, with 40 vendors—including none other than Lower East Side legend Katz’s Delicatessen stacking its signature deli sandwiches. Other names may look familiar: Ample Hills Creamery, Arepa Lady and Bunker all made the lineup. But also be on the lookout for purveyors debuting their first brick-and-mortar outposts, with poke at Wiki Wiki, bakery treats at Pop Cake Shop and Chinese street food at Jianbing. The massive space also hosts daily entertainment and programming, with a custom show kitchen and a stage for live concerts.
