Windy City does a good job and I will frequent them again in the future. The waiting room is dimly lit with plenty of seating and giant windows to watch your car getting cleaned. They seemed to put a lot of detail into every car. I was particularly impressed by my windshield being spotless after the full service wash, as it was extremely dirty after a long road trip. The tip jar is located by where you pay, similar to a mailbox. I thought this was a clever idea. On a busy Tuesday morning I spent about 40 minutes total there, but my car was being tended to the entire time. The price point is exceptional as well, as similar car wash places easily charge at least $10 more for the same or lesser work. I plan on coming back monthly. The owner, Nick, is also very accommodating and puts his guest's needs as his first priority!
