Urban Greens Food Co-op will hold a fall fiesta at AS220 in celebration of the local food system, the power of co-operative structures and the organization’s recent progress. Chefs from local restaurants, including Julians, Local 121, Louie Fullers and more, will prepare small plates featuring ingredients from local farms and producers. Proceeds from special beverage sales at the bar will benefit the co-op. Entertainment includes a silent auction, children’s activities and live music as the event culminates in a benefit concert. Local bands and musicians will play until midnight.
