Did you think you'd be dining under a highway overpass on your trip to Mexico City? Odd as that may seem, the tacos here are worth it. In fact, we'd say they're some of the best in town. There's a wide variety of both taco fillings and toppings, but we're particularly fond of the chorizo tacos with nopales and grilled onions. If you're adventurous, try the Chupa taco which contains (or so they claim) over 100 secret ingredients, many of which are meat...of some sort. By the way, the chupacabra is a mythical creature, akin to a vampire and known as the "goat sucker".
