First off, remember it’s fast food, standards are abysmal.
But it’s an actual piece of chicken, that’s actually prepared correctly.
If you got it in a sit down restaurant or even pub, you wouldn’t comment on it.
But compare it to any other chicken sandwich you could get from a drive thru in the last 20 years and the hype makes sense.
No matter where you are, if you see a chicfila you know you’ll get a decent chicken sandwich that isn’t ridiculously expensive.
A burger place isn’t going to do chicken as well as a dedicated chicken place, and KFC is a joke, so the only real competition for that niche is Popeyes on a national level.
