This is the real deal folks. Came to Austin looking for legit tacos, and finally found them on my last night in town. When you see that al pastor turning on that trompo (vertical spit), with the pineapple above it, you know you've come to the right place.
And any place that has lengua (beef tongue), tripa (beef tripe), buche (pig stomach), and cabeza (beef head) is not messing around. There are plenty of tamer options for the less adventurous, but get outside your comfort zone and try something new! Lengua has been one of my favorites for years, but tripa is quickly giving it a run for its money (and for the longest time I thought I didn't like it!).
Quality tortillas, excellent meats, A+ service, and open late - what more can you ask for? If I were an Austinite, this would be my go-to taco spot!
