Ruby’s Tortilleria is a small hut in the corner of a large gravel parking lot on Camino del Pueblo in Bernalillo. Residing inside that building is a feeling you'll find in small towns up and down the Rio Grande. You're in the heart of New Mexico but completely south of the border in spirit. If the phone cards, paletas and corrido CDs don't give it away, the green tomatillo salsa should. And on weekends, Ruby's turns the experience up a notch with juicy Mexican barbacoa.
