McDonald's Launches Big Arch Burger: All Your Favorite Flavors in One Delicious Bite
- McDonald’s is introducing a new burger called the Big Arch, featuring two quarter-pound beef patties, three slices of white cheddar cheese, pickles, lettuce, crispy and slivered onions, all on sesame and poppy seed buns, topped with a tangy Big Arch sauce.
You pull up to the McDonald’s drive-thru window, but when it’s time to put in your order, you freeze: should you get a Big Mac? What about a Quarter Pounder instead?
The fast food giant says that with its new offering, you can get the best of both worlds. Beginning March 3, McDonald’s is rolling out the Big Arch burger, which it promises will deliver “a premium flavor experience” with a dream team of ingredients.
