Business Insider asked more than 3,000 readers of our coverage about the best and worst chains in the US. It's unscientific, but informative about the predispositions of people who are engaged with fast food.

We crunched the numbers from the panel, creating a service score based on the percentage of people who visited a chain in the last six months and who said the brand had the best service. By creating this percentage, regional chains wouldn't be penalized for being smaller (i.e., In-N-Out wouldn't have a low customer service score simply because many people on the East Coast had never visited).

In the case of most chains — including McDonald's, Burger King, and Subway — fewer than 10% of respondents said that they believed the brand had the best customer service in the industry. However, a handful of chains stood out for having superior service.
