Popeye's is a fried-chicken chain with a New Orleans theme. They have sides like etouffe and red beans & rice, and their batter tends to be a little spicier than the other fast-food chicken chains. It's a watered-down version of cajun/creole, of course, because that's what fast food chains do.
Popeye's, like Church's, tends to place restaurants in black neighborhoods, where KFC targets white neighborhoods and Zaxby's targets the suburbs. That's based on what I see in the South -- I haven't done a comprehensive survey nationwide.

Popeye's was started in New Orleans in 1972 by Al Copeland.
