This is as good as it gets, Which would you rather have, a tunnel wash spraying your car (with a possible "hand dry") or 4 guys doing a real "hand wash", a definite hand dry and inspecting ever inch of your car to make sure nothing has been missed? You can watch the entire process, from beginning to end, from the comfortable waiting area.
Nick and his crew are pros and I definitely walked away from Windy City thinking I'd just discovered a hidden gem.
