I just heard the man who runs this website on NPR, and I thought it would be a potential resource to share. He has always been interested in food and cooking and wanted to do something to highlight and promote Black-owned restaurants and food businesses. There's a directory of Black-owned places in Chicago, New Orleans, and other cities. They are also doing a Blacktober - restaurant specials each weekend of October. It seems like that's only being promoted on Instagram. I had a hard time finding more information about it on the website. Here's a link to the Chicago directory of restaurants:
