Chick-fil-A buns are brioche buns.
Chick-fil-A uses toasted multigrain brioche buns, which replaced the original multigrain bun.
For example, Chick-fil-A's, grilled chicken club sandwich is made with a lemon herb marinated boneless breast of chicken that is grilled for a tender and juicy backyard smokey taste and is served on a toasted multigrain brioche bun with Colby Jack cheese, applewood smoked bacon and green leaf lettuce and tomato.
It's one of my favorite Chick-fil-A sandwiches.
