On two separate nights this summer, Mayo Civic Center’s Riverfront Plaza was alight with paper lanterns, cheerful reunions, and healthy arrays of international foods and artisanal goods. That vibrance is a hallmark of the Night Market, an event founded by Tiffany Alexandria as a way to bring a bit of Asia to the Med City. The third and final Night Market for 2021 runs from 5 p.m. to 9 p.m. on Saturday, September 18 at the Mayo Civic Center and Rochester Art Center.
