McDonald’s just launched its first new permanent menu item in 40+ years—the Big Arch! This beast has two 1/4-lb Irish beef patties, three slices of cheese, crispy onions, pickles, lettuce, and a brand new tangy sauce. It’s nearly four times the size of a regular burger and clocks in at 1,057 calories. People are already raving about it online, calling it “messy but good.” Would you try it for $10? #Food #McDonalds #BigArch
