I have not had Popeye's chicken in years; the nearest one I think is in Minneapolis, and it's not worth the drive. From what I remember, it was pretty good but not great; about the same as KFC extra crispy if you added just a little cayenne. And the sides were better than the chicken.
Hy-Vee (MN and IA grocery chain) sell their own version of spicy fried chicken, and it's better than Popeye's or KFC when you get a fresh bucket. KFC is better if Hy-Vee is having a bad day.
