Best of Boston

For a truly top-notch taco, you’ll have to head west—all the way to Waltham, that is, where this tiny taqueria stuffs its pliant corn tortillas with rich carnitas, tender braised lengua, and fruity al pastor—style pork, then serves them with a side of fiery, arbol chili—laced salsa. Request a pristine slice of avocado on top of each taco—you made the trip, you deserve it.
