In 2023, the British arm of the almighty McDonald’s corporation debuted a brand new burger: The Philly Cheese Stack. This flagrant ripoff of our beloved Philly cheesesteak has returned annually to McDonald’s locations all across the United Kingdom ever since. While this sandwich has yet to see a national release in America where it belongs, one domestic location is currently offering the burger for sale: McDonald’s Global Headquarters in Chicago, Illinois.

Yes, the ground floor of MHQ (the official corporate acronym for McDonald’s Global Headquarters, keep up) features a fully-operational McDonald’s restaurant with a rotating selection of Global Favorites. These Global Favorites occasionally join the nationwide McDonald’s menu, like the recent Big Arch burger, which I actually tried for the first time at MHQ months before its wide release. I stopped into this international McDonald’s during a recent visit to the Windy City; here’s what I thought of the elusive Philly Cheese Stack.
