Finally got to try both versions at lunch today.
The original (mild) version is set up like a Chick-Fil-A sandwich. The chicken was cooked properly, hot and juicy with a crispy exterior. It was not bad. I’d put it just below Chick-Fil-A on the scale of fried chicken sandwich goodness.
The spicy version was better. In addition to a spicier filet, it also came with a semi-spicy sauce that really brought the sandwich together for me.
Synopsis - Don’t go out of your way, but worth a try if you are eating at Popeyes.
