Yep, it's true. But it is only in two locations.
It is called McPizza - and people travel from all over the U.S. (and Canada) to get it. According to Eater, the McPizza was introduced to McDonald's stores across the country in the late 1980s and was available until the late '90s.
Today the McPizza is still available at two McDonald's locations in Pomeroy, Ohio and Spencer, West Virginia.
