In which decade did Carl's Jr. first expand outside of California?

Carl's Jr. first expanded outside of California in the 1980s. During this decade, the company began to grow its presence beyond its home state, marking a significant shift in its business strategy. This expansion involved opening new restaurants in various states across the U.S., which was a key factor in the brand's development and national recognition.

The choice of the 1980s reflects a critical period in the fast-food industry where many chains were starting to broaden their horizons and tap into markets outside their original locations. This strategic move allowed Carl's Jr. to introduce its menu and branding to a wider audience and is seen as a pivotal moment in the company's history.
