As a capstone to three years of work by USAID LENS in food processing, Jordan Food Week (JFW) attracted twenty-five thousand individuals in July 2018 to celebrate authentic Jordanian cuisine. This assessment finds that the event was exceptionally well-received by event-goers, and that it positively impacted the market system of restaurants, home-based businesses (HBBs), and artisanal food producers. Three out of four restaurants sold out at least once during the event and a majority of HBBs reported that they had insufficient products to meet demand at some point in the week. 40% of the HBBs report that JFW helped them increase their sales and half believe that it helped them expand their markets after the event. As a positive sign of sustainability, virtually all restaurants and exhibitors said they would participate again in the future, and 76% of HBBs said they would do so even in the absence of donor support.
