As Ed said & Walter says here Westworld were the chips. The tokens said Old Vegas though. No chips with this. Old Vegas was the name of the old mocked up town. I remember the 21 tables. I can picture them in my memory for sure. It sat vacant for years. Lots of brochures & paper came out when the auctioned stuff about 5 years ago in Vegas. Chips recently.
I used to go to ride the fast go karts. My dad would play the machines.
