Due to a licensing issue, the Kit Kats available in the U.S. are made by Hershey's rather than Nestle's and are (to my mind) made using inferior chocolate. Canada is much more into Kit Kats (theirs are from Nestle) and there seems to be a wider variety of flavors available in that country; I just picked up a bunch of Kit Kat Extra Dark Chocolate and they're almost too bitter to enjoy.
I miss the dark chocolate-orange version!
