Big Arch

What is it?

Two thin beef patties, three slices of American cheese, shredded lettuce, pickles, tomato, crisp slivered onions, and a tangy, creamy sauce all stack up inside a split sesame seed bun with a middle bread layer. Structurally it lands closer to a Big Mac, but with a different sauce and a more expanded topping set. Like other burgers in the McDonald's lineup, the patties are cooked on a flat-top griddle and the cheese is melted onto the meat. Tomato and onions set it apart from simpler chain burgers, while the three-bun build changes the bite from top to bottom.
