We asked 3,000 people who read our fast-food coverage which chains come out on top in all of these categories - and no one chain came close to Chick-fil-A. To avoid penalizing Chick-fil-A and other smaller chains, we only considered responses from people who said they visited a chain in the last six months and who said the brand was the best in a category.
In-N-Out regularly snagged the No. 2 spot in most categories, including best food and cleanest restaurants. But, Chick-fil-A's dominance is clear.
Why is Chick-fil-A thriving in a way other chains cannot imitate?
One thing that sets Chick-fil-A apart from rivals is that franchisees are only allowed to open a single location.
They don't have to pay much - unlike other chains - but the process of getting approved is extremely drawn-out and difficult. Once these franchisees have fought to be a part of the system, they are hands-on in making sure their locations are clean and offering top-notch service, which helps explain Chick-fil-A's high scores.
This model and other aspects of Chick-fil-A's business have helped the chain become one of the most successful in fast food.
The chain is the third largest in the US by sales, growing revenue by 16.7% in 2018 to reach nearly $10.5 billion, according to Nation's Restaurant News. Over the past decade, it has nearly tripled its annual sales.
