I did not know CEC was still around. Doing a little research, from Wiki...As of December 2022, there are 471 Chuck E. Cheese locations in the United States, and 97 locations in Canada (10), Chile (12), Puerto Rico (3), Guatemala (2), Saudi Arabia (24), The U.A.E (1), Trinidad & Tobago (2), Peru (9), Panama (9), Mexico (21), Colombia (1), Honduras (3), Costa Rica (1), Jordan (1), India (1), El Salvador (1), Bahrain (1), Suriname (1), and Qatar (1), a total of 568 Chuck E. Cheese locations across the world.
Showbiz Pizza acquired CEC in the 1980s and rebranded all Showbiz to CEC. I suspect the number of locations was higher in the past than the current 471 in the USA. I know of one locally that closed up several years ago...not because of a shooting, though. I went to one in Minneapolis in 1982 or so. Don't remember the pizza but remember playing Battlezone.
