• Technomic data analyzed by Nation's Restaurant News ranks the top 15 US fast-food restaurants.

• Starbucks, Chick-fil-A, and Taco Bell also ranked highly.

In the US, fast food is king. However, some chains are simply bigger than others.

From McDonald's to Taco Bell, quick-service and fast-casual chains fared far better last year compared to casual-dining chains like Chili's and Applebee's, Restaurant Business reported in June. However, those chains are attempting to level the playing field this year with value-focused initiatives and comparable menu items — and it might be winning customers over.

The research firm Technomic recently identified the top 500 biggest chain restaurants in the US. The report, which Technomic said is based on "decades of historical data," analyzes trends in the food service industry and includes each chain's annual sales and unit counts for 2023, which were also reported by Nation's Restaurant News.

We looked at the top 15 chains listed as quick-service or fast-casual. We didn't include casual-dining or family-style chains like Cracker Barrel or Applebee's in this ranking. We also listed the year the company was founded, its 2023 sales, and restaurant count, per Technomic's report.
