We lived just north of Wheaton and they were on the way and open late for trips home from the restaurant. Their pupusas are beyond category. La Familiar and La Casita are the class of pupusas in Maryland. If they are as good in Falls Church, they will be one of the best spots around.
Steve. Have you tried Taqueria Picoso in Alexandria? It is right by Mark Center not far from the Clyde’s on Beauregard. They make their own masa and the food is very hearty and earthy. They have people with chops in the kitchen and you can really see it in the food.
