At the annual Mole de Mayo Festival, thousands of hungry Chicagoans come to explore the authentic Mexican flavors of the Pilsen neighborhood. This year's festival marks the eighth anniversary of the event, where locals and visitors come to taste some of the best mole dishes in Chicago. Each year Mole de Mayo features a mole contest, where restaurants compete with their versions of the Mexican staple. The festival is organized by the Eighteenth Street Development Corporation, a non-profit organization that has been serving the Pilsen neighborhood for more than three decades.
