"This tiny spot in a nondescript part of the city center is known for one thing: succulent tacos de cabeza de res (tacos made from the meat from the head of the cow). Don't let that freak you out; they're delicious."
"Los mejores tacos del centro histórico’ (‘the best tacos in the historic centre) shrieks the sign at Taquería Gonzalez on the corner of López and Vizcainas — and, judging by the huge crowd gathered at the corner, they might just be right. The tacos filled with cabeza (oven-roasted cow head) are delicious."
"Tacos of oven roasted sheep head may be only for the adventurous eater but they are delicious. Everything “cabeza” is offered at the popular stand-up-only hole in the wall. Lengua, (tongue), buche (lips), oreja (ear), nothing’s wasted here."
