Yes, we’ll head to 5th Street north of Girard in search of the authentic, exuberant Mexican at this cheery, bilingual, cash-only taqueria. In fact, we’d move for the salmon taco alone. Neighbors indulge daily in steaming foil-wrapped burritos with fajita-style fillings, almost more than a dozen variations on the taco (including some unusual-in-the-U.S. beef options), and hearty breakfast choices.
