A drive-thru customer satisfaction study has found that Chick-fil-A and Dutch Bros are among the top performers. The study also evaluated other aspects of the drive-thru experience, including speed and food quality, with Taco Bell reportedly exceling in speed and Raising Cane's in food quality. However, there are conflicting reports about which chain has the fastest drive-thru, with some outlets citing Taco Bell and others suggesting Chick-fil-A has the slowest wait times.
