I ordered a "taco de cecina enchilada"... pork cecina sprinkled with chili powder.
There is not much to it... just a slice of "cecina" on top of a tortilla, and three different kinds of salsa to spoon on. Roll up the tortilla around the meat and eat. It was good... in fact I ordered a second one.
I plan to return to this place. I definitely want to try the stall selling Yucatecan food.
