The Mushroom Capital of the World hosts this town-wide celebration the weekend after Labor Day every year. The Kennett Square Mushroom Festival is a Brandywine Valley tradition, a mile-long street fair with nearly 250 vendors and every kind of mushroomy treat you can imagine – mushroom soups, mushroom pastas, mushroom risottos, mushroom enchiladas, mushroom ice cream, and more. Celebrity chefs often pop up for food demonstrations, and restaurants set out tables for al fresco dining and dancing after the annual Mushroom Parade.
