Most everyone has heard about the KFC Double Down in the US. Bacon, sauce, and cheese between two fried chicken patties. But KFC South Korea just looked at that, laughed, and gave its people the Zinger Double Down King, which was the same fried chicken instead of buns idea, but instead of just bacon and cheese between the fried chicken, there was a beef burger, bacon, cheese, barbecue sauce, and a white pepper sauce.
