McDonald’s is testing its most caloric sandwich yet—the Big Arch—in Canada, Portugal, and Germany. With 1,030 calories, two beef patties, and a custom tangy sauce, it’s a burger lover’s dream!

Some corporate fast food secrets are fiercely protected, but it's no mystery why McDonald's apple pie tastes the way it does.

Instead of Ronald McDonald, Speedee tops the single-arch sign. It’s a vestige of vintage style you can still visit. Head to 10207 Lakewood Blvd, and this old McDonald’s will greet you.
