On Wednesday, July 25, 2012, the Chicago City Council is expected to take up an ordinance that would allow chefs to cook and prepare food onboard the trucks and creates parking zones around the city. Chicago, known for its high-end restaurants, has lagged behind other cities when it comes to joining the food truck craze. (AP Photo/Sitthixay Ditthavong, File)
