If you win a couple years in a row good for you but if you're the restaurant that was chosen for the sixth straight year as America's favorite fast food chain then you're definitely doing something right! According to American Customer Satisfaction Index Restaurant Report 2019-2020, Chick-fil-A was chosen for the sixth year in a row as America's favorite scoring 84 out of 100. That's actually a 2% drop from last year. Unfortunately the restaurant that scored the lowest rating was McDonald's. The rest of the top five went to Chipotle Mexican Grill, Arby's, Domino's and Dunkin'. Any guesses as to which restaurant topped the list of our favorite full-service restaurant?
