What fast-food restaurant chain is Carl's Jr. commonly compared to?

The choice of Hardee's as the correct answer stems from the fact that Carl's Jr. and Hardee's operate under the same parent company and offer a similar menu. In many regions, Carl's Jr. is known for its charbroiled burgers and other fast-food items, much like Hardee's, which has a comparable offering but often caters to different geographical markets. This similarity in branding, menu items, and overall operational style leads to frequent comparisons between the two chains.

While McDonald's, Burger King, and Wendy's are well-established competitors in the fast-food industry, their business models, menu specialization, and marketing strategies differ more significantly from those of Carl's Jr., making Hardee's the most fitting comparison.
