Okay, so Alexandria isn't technically in D.C., but The Dairy Godmother is WELL worth the detour. Located in the DelRay neighborhood of Alexandria, VA, this ice cream shop is just a stone's throw from Washington and can be easily fit into your day of touring historic OIde Towne Alexandria. The Dairy Godmother boasts old fashioned spun frozen custard. The owner is from Wisconsin where the real deal comes from, and her flavors are amazing! Flavors change about every other day and include the oldie-but-goodies of chocolate and vanilla but rotate in Coconut Cream, Dementor's Kiss, Kulfi, Toasted Almond - the list is endless. She also always has a vegan sorbet option. President Obama took First Tweens Malia and Sasha Obama here on Father's Day - you can even sit where he sat to enjoy your cone.
