Okay, so I got Popeyes tonight. Overall very favorable impression!
Fried chicken -- very good. I got the 3-piece dark meat combo. I used to live in southern Arkansas and my great-grandmother would fry us up some chicken that was very similar--way crispier and crunchier than KFC's "surface only" seasoning. I got the spicy chicken, which wasn't too hot.
Biscuit -- definitely a standout. very fluffy and buttery compared to KFC biscuits, which tend to be dried out. I should have gotten an extra biscuit or two on the side.
Potatoes -- surprisingly good with their spicy "cajun" gravy that managed to add a fun flavor kick without overpowering the potatoes.
I dunno if I would make the drive every time I want fried chicken, but I'm definitely glad to have given it a try and can now say with first-hand knowledge: Popeyes is yummy!
