I have been to this show many times and even set up there one year.
For those who have never been there, here in some information.
Officially called the Chicago Coin-Op show, originally started to profile coin operated items, now "if it shines, it is fine." Meaning you can find just about anything that will go in a gameroom or a 50's bar. There will probably be a few restored gas pumps, but this nothing near being a petroleum show.
Be sure to check out the trucks outside, this is where the unrestored items are usually sold. A great place to buy a working jute box for around $400 - $500, not a bubbler, but a box that plays 45s.
Two large rooms, it usually doesn't take more than 4-5 hours to really look at everything. The charge to get in on Friday is $50.00 per person, on Saturday and Sunday it is $5.00. The show is held in St. Charles, Ill, west of Chicago, north of I-80.
