Ashlee Rezin Garcia/Sun-Times Things are a bit of a mess in the 4100 block of North Rockwell Street. A steady flow of Uber Eats, Grubhub and other delivery drivers picking up food from a commercial kitchen on the block, neighbors say, is disrupting life and creating a dangerous environment for pedestrians. Cloud Kitchens — which was founded by former Uber CEO Travis Kalanick and has locations across the country, including five in Chicago — opened for business on Rockwell in July. The company bought the building, remodeled it and rents kitchen space to restaurants including Chick-fil-A to fill online orders only. There is no dine-in space.
