This holds a big place in my childhood memories. We would save up to buy a bar of kit kat and that would be our treat. The size is what makes it so convenient, especially now when you're rushing and you don't want to be holding a goeey bar of chocolate.
That combination of a crispy wafer with tasty milk chocolate works well and makes for a satisfying snack. It is also available in a variety of convenient sizes and fun packs.
Overall, the original kitkat from nestle is a good quality, chocolate snack and a tasty treat.
