The KFC near me in the U.S. wasn't bad, I haven't eaten out at all since the pandemic. Maybe because it was usually busy at lunch when I went, all the food was fresh. I used to get a breast, a side, a drink, and a cookie for $5, that was a decent lunch. If I went in outside of busy times, yeah, the food had obviously been sitting around for a while, but it was still good enough for five bucks.

Like all fast food, the quality can vary considerably from store to store, and region to region.
