6. White Tower
The first White Castle opened in 1921, and became the first popular fast-food chain. As is prone to happen in business, numerous imitators quickly opened. One of these knockoffs was known as White Tower. Opened by John E. Saxe and his son, Thomas, White Tower copied White Castle’s menu, style, advertising, and even architecture. At its height, there were 230 White Towers, but the chain died after legal action from White Castle forced them to make significant changes.
