As you enter Tijuana Taco Shop, note the narrow counter to your left. It’s much like you’d find at a Mexican taco stand and a sign that the Demucha family is serious about authenticity. The feel just gets better as you enter the cozy cantina, which is equipped with Dos Equis on tap and an assortment of tequilas. Settle in the dining room at a tile-top table or in a comfortable booth amid the cheerful sounds of Mariachi music. The fish tacos (grilled or broiled tilapia) and enchiladas with mole are all the rage. Other reasons to visit Tijuana include a fajita in a burrito wrap topped with melted cheese, lobster bisque (call ahead to see if it’s available) and the shrimp taco salad.
