There is a chicken and waffles restaurant here in Louisville. I don't think it's a racist thing at all, in fact, the guy who opened the restaurant is African American. I think it's just southern soul food.
I googled the restaurant and here is an excerpt from one of the reviews:
The chicken-and-waffles combination is one of those strange culinary phenomena whose origins are tough to pin down. Chicken-and-waffle places are often seen in urban African-American neighborhoods in such cities as Los Angeles and New York, but are also found in Pennsylvania Dutch country at church suppers. Some folks even claim that mixing chicken with waffles originated in Louisiana.
