When we were driving through Flagstaff, Arizona, we were hungry for lunch and were craving Mexican food.  We stumbled upon Kachina Restaurant on Route 66.  This is not a brand new restaurant but it has a comfortable, family atmosphere.  We ordered the beef burritos with sides of beans and rice.  The kids ordered grilled cheese and chicken fingers.  The burritos were gigantic and very tasty!  The kids enjoyed their food as well. The service was also good.
