They're American restaurants. Wendy's specialty is burgers and KFC's specialty is chicken. Their foods are delicious, calorie loaded, garbage that no one should eat. XD
Compared to the other fast food places I've been to. It's better than McDonalds, better than Burger King; it's a higher tier fast food place. I wouldn't really say it's necesarily "high tier", rather probably a mid-high tier.
