The Open Market fundraiser for the Meatpacking District Improvement Association on Monday evening filled the Highline Stages, at 441 W. 14th St., with an endless array of tasting stations brimming with samples of delicious food and drink from the district’s many trendy restaurants and bars. Clothing from local boutiques was also for sale at cut-rate prices. Outside Highline Stages, Meatpacking District luminaries gathered, from left, hotelier André Balazs; Joshua David, co-founder and president of Friends of the High Line; fashion icon Diane von Furstenberg and Mazdack Rassi, founder and creator director of Milk Studios. M.P.I.A., which is not a business improvement district, is in the process of trying to create a formal BID for the area.
