How the ranking was determined

The American Customer Satisfaction Index gathers information from 500,000 customers interviewed annually and inputs it into a multi-equation model developed at the University of Michigan. Unlike other organizations that measure things like revenue and volume of customers or purchases per year, the American Customer Satisfaction Index is unique in its focus on customer experience and satisfaction.

This year's restaurant study was based on interviews with 16,250 customers, chosen at random and contacted via email between April 2022 and March 2023.

According to the research, customers care the most about a number of experiences and customer service-related components. In ranked order, they are:

• Accuracy of food order
• Quality of mobile app
• Reliability of mobile app (minimal downtime, crashes, lags)
• Beverage quality (taste, temperature)
• Courtesy and helpfulness of staff
• Food quality (taste, temperature, freshness of ingredients)
• Website satisfaction
• Restaurant layout and cleanliness
• Speed of check-out or delivery
• Variety of beverages on menu
• Variety of food on menu
