For beef burger fanatics in the United States, the fast food chain In-and-Out is famous for offering secret burger combinations, if you know how to ask for them. The most outrageous secret beef burger, known as the Monkey Style, combines some of the most delicious burger toppings to create one massive jungle king-worthy burger.
For those who manage to crack the code on In-and-Out's secret burger combinations, the Monkey Style burger does not disappoint. A spin on another top-secret burger called Animal Style, Monkey Style combines a beef burger cooked in mustard, lots of pickles, extra thousand island dressing-like sauce and grilled onions with french fries layered on top. Together, these delicious ingredients create one messy burger that barely fits in the palm of your hand. As for the name, this burger is definitely monkey-crazy.
