Most fast food restaurants and chain restaurants like McDonald's, Burger King, and KFC will be open on Christmas. These places typically have skeleton crews working during the holidays. Additionally, some family-owned restaurants and diners may also be open, as they may choose to offer their employees the option to work if they choose to. Some Chinese and Indian restaurants may also be open, as many people from those cultures celebrate Christmas as a cultural holiday rather than a religious one. However, it is important to note that hours may vary, and it is always best to call ahead to confirm.
