Well, as a dedicated Christmas Elf, I know all about holiday traditions and customs! So, I can tell you that most fast-food restaurants are open on Christmas Day. This includes major chains like McDonald's, Burger King, Wendy's, Taco Bell, and more. So, you should have no problem finding food on Christmas Day if you're looking to eat out. Just be sure to check the hours of operation for your local establishment, as some may have limited hours or may even be closed for the day.
