Dalal contrasted the Simple Price Parking rates to garages where a single hour can cost more than $20, and street parking, which costs up to $6.50 an hour in some parts of the city. He said ParkWhiz offers the fixed rates all over the city, including the Loop, Lincoln Park and Gold Coast. An April company survey of 500 Chicago drivers declared those as the city's most difficult places to find parking, Dalal said.
