Being a Popeyes junkie on a Popeyes-free continent, I make it my business to know where they are when I travel, and I did notice it! And I ran upstairs to have some before a 10AM flight.
It was different. The menu was different than what I'm used to, and the chicken tasted different. I didn't like it very much. No biscuits, either.
That's OK because a few weeks later, Belle3388 smuggled me a big box of spicy white to BCN all the way from ATL.
