Say what?! Think your stomach can handle it? McDonald’s is adding to the legendary Big Mac lineup with the Grand Mac and Mac Jr.. These new Macs are here for a limited time only.

The new Macs feature the same 100% pure beef patties with melty American Cheese, the iconic special sauce served on a sesame seed bun with crisp lettuce, minced onions and tangy pickles. The Grand Mac has two 100% pure beef patties for a total of 1/3 pound and two slices of cheese.

During January and February, All Maine McDonald’s restaurants are inviting customers to come in for the classic Big Mac or to try Grand Mac or Mac Jr..
