The Pretzel Bacon King is new for BK, although Wendy’s has one from time to time that is similar.
The burger version has multiple patties, cheese, bacon, mayo, and mustard on the new Pretzel Buns.
They however are really emphasizing at participating locations more than usual. Since this is actually BK Canada’s sandwich being rolled out in the US maybe supplies are limited. IDK.
Exact pricing isn’t available because my BK location doesn’t have it yet, but they said check back soon they may have the sandwich as soon as Monday.
