They seemed to be so popular in the 1990s and early 2000s, but seem to have been disappearing from the scene. McDonald’s still has them and still puts them in new and remodeled restaurants. I would like to know how fast food restaurants originally had outdoor playgrounds and then changed them to indoor playgrounds instead of just having the indoor ones to begin with. And why have so many of these restaurants taken them out and not replacing them. I would like to hear what you think.
