Chick-fil-A breakfast service typically ends at 10:30 a.m. This applies to most locations Monday through Saturday, with the restaurants being closed on Sundays. After 10:30 a.m., the breakfast menu is no longer available, and customers are served lunch options instead. Some locations may have slight variations, but 10:30 a.m. is generally the hard cutoff time for breakfast at Chick-fil-A.
