We've already tested the Chicago Med cast on their knowledge of all things Chicago, but how do their Chicago P.D.colleagues measure up?

During a recent set visit, TVGuide.com gave Chicago P.D. stars Sophia Bush, Jesse Lee Soffer, Patrick John Flueger, LaRoyce Hawkins and Jason Beghe a pop quiz about Windy City trivia - ranging from where deep-dish pizza originated to the number of times Da Bears have won the Super Bowl. It's only fair to note that Hawkins, who grew up in Chicago, probably has an unfair advantage here. But how did his co-stars do? Watch the video above to find out.

Chicago P.D. airs Wednesdays at 10/9c on NBC.
