This taco stand is right on the Carretera Nacional on the way from Monterrey towards Santiago. They are right besides a 7-Eleven at the intersection of the El Faisan community. They always looked packed so we stopped by for dinner and I have to say they are one of the best pastor tacos I´ve had in my life!
They also have a sitting area so you don´t have to stand outside. They have the usual, carne asada and trompo (grilled beef and pork), with or without cheese. They also make some monster hamburgers that rumor has it are very good (haven´t tried those).
They also have baked potatoes stuffed with everything! They are the perfect meal after a party to avoid the hangover... Their portions are rather big, so 3 or 4 tacos feed a good eater. The staff is really friendly, though they do not speak English, but if you can count to 5 and pronounce trompo or carne asada and con or sin queso you will be just fine!
