It was the tweet heard around the world. On February 9, the official account of the City of Chicago wrote “proud to be the pizza capital of the world.” The reactions in the Twittersphere and beyond were unsurprisingly swift and impassioned.

Phil Murphy, the governor of New Jersey, immediately responded with “I’m incredibly proud to be Governor of the Pizza Capital of the World,” while Italian actor Salvatore Esposito made it clear to Chicago that they were a distant second to Naples. Even after the keyboard dust settled, there was no clear victor. So is there truly a pizza capital of the world out there?
