This behemoth of a burger is stuffed with proteins from the Land (beef), Sea (fish), and Air (chicken). Some people even add fries to this monster burger. You order a Big Mac, a Filet-O-Fish, and a McChicken all at once. Then you put the McChicken and Filet-O-Fish patties inside the Big Mac along with however many buns you want (depending on how wide your mouth will open) and enjoy! Voila - a Land Sea and Air Burger ! How tasty does that sound? So, if a normal Big Mac doesn't quite fill you up, take a chance by creating a Land, Sea, and Air Burger from McDonalds Secret Menu. In our opinion, the Land, Sea, and Air Burger is more than enough to satisfy anybody's appetite. When ordering, don't forget to order a big drink to wash it down!
