According to the Huffington Post, “Chicagoans might have to sit down for this one.”

“For years, the battle between New York and Chicago pizza has raged on. Though some argued that a floppy New York slice is best, we knew it was no match for our cheesy deep dish, crisp thin crust and delicious sauce. When Chicago native Michelle Obama headed to the White House, we were glad to have a first lady repping the Windy City, but during a Thursday trip to a New York pizzeria, Obama uttered the words no food loving Chicagoan wants to hear: “It’s the best pizza, and I’m from Chicago.”

Obama, daughters Malia and Sasha and their grandmother Marian Robinson all were in New York Thursday to check out a musical and eat lunch at Grimaldi’s, a popular pizzeria beneath the Brooklyn Bridge. Ralph Harajda, a waiter at Grimaldi’s, told the New York Times blog that Obama was “very pleasant to serve” and a “very generous” tipper. No problems there.
