Cost: $6.99 (With Big Mac)
$4.00 (With McDouble)
The concept, similar to that of KFC’s infamous “Double Down” packs beef between McDonalds’ tender McChicken patties.
With this crazy, secret option comes the ability to pack either a Big Mac or a McDouble between the chicken patties. Go big or go home, in my opinion, but either offers any meat lover a delectable combination of some of the best sandwiches McDonald’s has to offer.
