12 Tasty Secret Items From McDonald's

9. The Monster Mac

Cost: $6.49

Not just two patties, not just four, not just six, but a whopping eight beef patties all crammed into one giant Monster Mac.

This jaw-dropping creation lacks widespread popularity, simply because few consumers have the stomach to finish 8 patties at once. To order, simply ask for the Monster Mac, or if they aren't sure what you're getting at, say you want a Big Mac with eight patties.
