Don't bother trying it. It's gotten really bad over the years. The chickens have gotten smaller, and now they cut the normal 9 pieces of chicken in half in order to get more out of a chicken and provide extra mechanically separated meat for all the new sandwiches. There are much better fried chicken places around.
It's not even like the kind of phenomenally bad that you have to try, it's just the most completely mediocre fried chicken you can imagine. Last couple times I tried it (in laws always order it when we visit for some reason), it's been soggy with grease, not even crispy, and all the oil stops you from really tasting anything. You might as well just slop some bread crumbs into some vegetable oil if you really want the KFC experience.
