The rankings appear to be based on customer satisfaction, with different sources citing various chains as the best for specific menu items, such as burgers and breakfast. The exact rankings and top chain are unclear, but it is reported that Chick-fil-A, previously a top-ranked chain, has been surpassed by another restaurant.
