KFC, which originated in the United States, is a world-famous fried chicken fast food chain with more than 10000 restaurants all over the world.

McDonald's is a chain-operated fast food restaurant, which was founded by McDonald's Brothers and ray kroc in the 1950s in the United States, mainly selling hamburgers.

This also clearly illustrates the difference between them.

One prefers hamburgers (McDonald's) and the other prefers fried chicken.

In terms of packages, McDonald's has more hamburger packages, while KFC pays more attention to fast food, drinks and snacks.

There is only KFC in Xinjiang, but there is no McDonald's. The reason is that McDonald's has pork cooked food, which is not halal.

McDonald's has milkshakes, but KFC doesn't.

The sundaes in the two stores have different tastes.

McDonald's has breakfast, but KFC doesn't (not sure).

The above is my answer a few years ago, plus one from Pizza Hut.

Pizza Hut is one of the largest pizza chain stores in the world. Frank Carney and Dan Carney set up the first Pizza Hut in Wichita, Kansas, USA in 1958 with $600 borrowed from their mothers.

Pizza Hut's main food is the same as their logo, that is, pizza (two specifications, n flavors, and more western and Chinese styles have been added in recent years), and incidental drinks, fried food, cakes and snacks (fried more) are not bad. I strongly recommend their drinks, which basically change every quarter, and the price is between 20 and 60, which varies according to different regions.
