If the mood strikes you on Christmas morning, you can always have waffles and sausage for breakfast. In fact, if there's no place else open on Christmas Eve you can even have waffles and sausage for Christmas dinner at a Waffle House. There are over a thousand Waffle House restaurants open on Christmas and on every other day of the year as well. According to the official Waffle House website, "Waffle House® restaurants are open 24 hours a day, 365 days a year (including Thanksgiving, Christmas and New Year's Day)."
All you need to do to find the restaurants closest to you is to go to their Waffle House Restaurant Locator at their website and enter your address, city, state or zip code in their search engine. A Christmas breakfast alternative to waffles is IHOP but remember the Waffle House slogan, "Friends don't let friends eat pancakes."
