Yes in Mexico everything is tacos. And they have any kind of taco you can think of. I had a pork taco, thought it was bomb. I am not too much into black beans. I actually went out one night looking to score some drugs and met some cartel dude who was associated with a huge Taxi company. The drivers were drug runners. I smoked a blunt with the mexican dude and he took me back to this building in the slums of Valladolid (I do not reccomend travel here) and I picked up a huge bag of coke on the cheap. We smoked, drank some beers, ate some gnarly lookin food that could have been confused with tacos but it was some kind of seasoned chicken chilantro, lime, pineapple.. Idk what they were but the shit was nasty. I just remember being all fucked up and I kept joking with the guy asking if he was gonna shoot and decapitate me and he pulled out of gun and went "boom boom" and laughed... so we did some more coke and I paid him and got a cab ride back to the city.. caught a bus to cancun. it was awesome actually.
