Two more entries have been added to the seemingly ever-expanding shopping options on Bergen between 5th Avenue and Flatbush. Already open is a branch of Lululemon, the yoga clothing/accessories store that was profiled for its cult-like following in last week’s New York mag. Then, right next door, fancy hot dog joint Bark is scheduled to open in about a week, according to its owners. Closer to 5th Avenue, meanwhile, the former Unnameable Books storefront is under wraps, and something new is evidently in the works there. There are now almost no empty shop spaces on the Pintchik-controlled block. GMAP
