Taste: Kit Kat has always been a favorite. There's lots to like. You've got the crunch and lightness of the wafer bar inside, providing a nice balance for the chocolate. There's also the fun of breaking off the four individual bars, plus the convenience of being able to eat the four bars one at a time. But I think the main appeal is the great milk chocolate that Kit Kat uses. We compared this American Kit Kat (made by Hershey) to the British version of Kit Kat (made by Nestle) and found that this was half an inch shorter.
