I just took a driving trip around northern Kentucky and southern Indiana, and I was surprised to see how many fast food restaurants were promoting fish sandwiches on their outdoor signs. Not just McDonald's, but Wendy's, Rally's, and several others. Does anyone know why? Here in California, Filet-o-Fish is hardly a popular menu item.
Incidentally, I had a simple but very good fish sandwich at Cunningham's in downtown Louisville.
