There’s an entire museum dedicated to it
In North Huntingdon, Pennsylvania, a suburb of Pittsburgh, McDonald’s Big Mac enthusiasts can visit the world’s only Big Mac Museum. Jim Delligatti, the Big Mac’s original creator, and his son Mike developed the museum in 2007. It features attractions like a 426-metre Big Mac statue, historical memorabilia (including a Big Mac bun-toaster from the 1970s), and, of course, a McDonald’s restaurant.
Pittsburgh renamed itself after the Big Mac
Temporarily, yes, but they still did it! In September 1992, in honour of the burger’s 25th anniversary, Pittsburgh became “Big Mac, U.S.A.” for a single day. It was a tribute to the city’s proximity to Uniontown, the Big Mac’s birthplace.
Kazakhstan was the most recent country to start selling it
“More than 100 countries serve the Big Mac, including Kazakhstan, which most recently added it to menus in 2016,” Miesle told Reader’s Digest. The Central Asian nation’s first Mickey D’s opened on March 8, 2016, in the capital city of Astana to a large, eager crowd. As of August 2018, Kazakhstan is the 120th country to open a McDonald’s, but only the first in the region of Central Asia.
