If you want to have a good time in Chicago don't bother with Park One garages. We had some visitors come stay with us for the night and they paid for parking at a Park One garage. When they went to leave the next morning the car was GONE. It was towed because the ticket was a few hours expired. There was no standard rate and the sign was misleading (it did not say that the ticket expired at midnight no matter what time the itwas purchased at) It was a $30 cab ride to the south side of the city to the place where the car was towed and then another $175 to get the car out. Most people just get a ticket on the window for an expired parking pass but apparently they like to hassle out-of-towners. Don't park here. They are shady about pricing and insanely rude!
Pros: None, there are plenty of other places in the area
Cons: Rude and tow cars all the time
