Chick-fil-A serves breakfast from 6:30 a.m. until 10:30 a.m., Monday through Saturday. Breakfast service ends promptly at 10:30 a.m., and after this time, the menu switches to lunch and dinner items. Even if you are in line after 10:30 a.m., you may not be able to order breakfast. Chick-fil-A is closed on Sundays, so no breakfast is served that day
