Obama: Dissing Chicago Deep-Dish?

President Obama will have a pizza chef fly to DC to prepare lunch at the White House Friday--but not from his hometown of Chicago, birthplace of deep-dish and renowned for its pies. No: Ryan Mangialardo, partner in St. Louis's Pi restaurant, will be preparing what Obama has previously called "the best pizza I've ever eaten." (At least that's what Obama told Pi's owner over the phone after consuming Pi's delicacies in October, while in town for a rally that drew an estimated 100,000 spectators to the city's downtown area.) It is yet unclear precisely how betrayed Chicago's pizza chefs will feel.
