These may be the best authentic tacos in Austin. That's saying a lot and I'm happy to make this claim. I'm obsessed with this place. Cuantos serves tiny little 2-3 bite tacos, the kind you'd get on the street in Mexico City. Bring some beer to hang out (since the park is BYOB) and order everything from the menu. Bring friends and show them how cool and knowledgeable you area.
