what fast food restaurant is open on christmas day

That's a good question. Most fast food restaurants are closed on Christmas day, but some may have special hours or limited menus for the holiday. It's always a good idea to call ahead and check their hours before you head out. Some popular fast food restaurants that are open on Christmas day include McDonald's, Taco Bell, and Burger King. However, their menus may be limited to holiday items and their hours may be shorter than usual.
