Much of the touristy part of Chinatown is worn and ragged, but there's good stuff to be found and sights to see if you get off the main streets. Wander out to where the real people shop and eat and live. Parking is cheap in the big lot under The El station, but it can get filled early on weekends. Take the Red Line.
Pros: Plenty to see
Cons: Parking can be tough
