I drive by popeyes daily when runnign for lunch. Never that busy.
I went today, the drive thru was 16 cars deep. I went inside. 8 ppl in front of me. All but one ordered the chicken sandwich. They had a row of premade sandwiches ( classic and spicy ) and were handing them out as fast as they could.
And i honestly believe that if the sammich wasnt that good, it wouldnt be like this. But its a massive breast of chicken, with a spicy mayo combo and clausen pickles. And the bun reminded me of Hawaiian bread. Had a sweet taste to it that complimented the pickled and spicy mayo.
