The vault was set up as a quite impressive gamer-cave. There were purple LED rope lights lining the walls, and of course, beefy Wintel PCs to run all the games you could ever hope for in those heady days. It was supposedly rather difficult to run wiring into the vault; of course it wasn't designed for all of that, and the walls were not exactly conducive to drilling or sawing into it.
But they made it work for a few years. Those days of Internet Cafés were kind of amazing. Nowadays, we're lucky if the Free Starbucks WiFi is working properly.
