Howard Johnson's was once America's biggest restaurant chain. It had over 1,000 orange-roofed diners selling 28 flavors of ice cream and fried clams. In the 1960s it was bigger than McDonald's, Burger King, and KFC. The chain shrank for decades. Only one restaurant was left, in Lake George, New York. That last Howard Johnson's closed in 2022. Today there are zero left in America.
