El Carboncito is a great place to get some authentic Mexican street food, the Al Pastor is very good... especially in my favorite form of gringa quesadillas (pastor pork, Oaxaca cheese, onions and cilantro)! Yummy... heaven on a tortilla! They are only open later in the evening... that is when most of their customers are out... it is HOT prior to that. say 7:00 pm on or so. Well worth the visit!
