These Popular Fast-Food Chains May Be Closing Their Doors for Good

Quiznos

This fast-food chain specializes in toasted subs. Founded in 1981, the restaurant once expanded to nearly 5,000 locations, but by 2018, less than 800 restaurants remained in the U.S. In 2014, the company filed for bankruptcy, but Quiznos has found success overseas in places like Europe, the Middle East, and Asia.  

Carl's Jr.

In 1941, truck driver Carl Karcher and his wife Margaret purchased a hot dog cart in Los Angeles. Two decades later, Carl's Jr. had expanded throughout the state of California. Despite their popularity, Carl's Jr. has been consistently closing down more and more stores each year.
