Once a customer finishes their Challenge Set, they can get to work on nomming on all the Whoppers they could ever want, yes, there's a second catch, they only get a half hour to scarf down their precious burgers. Oh, yeah, there's a third little disclaimer, this deal only applies to the straight up O.G. Whopper, none of those fancy versions that have been in the news lately. If you happen to find yourself in Japan this month, this AYCE deal runs from November 4-13.
