Back in the day there were two Chuck-E-Cheese style pizza chains. Pizza Time Theatre (invented by Nolan Bushnell, aka inventor of Atari and Pong. He also invented the Chuck-E-Cheese rat character. Yes they were invented by the same guy) and Showbiz Pizza, which was a pretty solid "clone" of it. They were competitors for a while and then merged and renamed themselves Chuck-E-Cheese.
I know way too much about Chuck-E-Cheese. Don't ask.
