Discada proves that doing one thing exceptionally well can be more exciting than a giant menu. This East Austin trailer cooks beef, pork, and vegetables in layers on a plow-disc-style griddle, concentrating every savory edge before tucking the mixture into tiny corn tortillas. Order the tacos all the way with onion, cilantro, and pineapple, then decide how brave to get with the salsa. The prices are friendly, the format is wonderfully focused, and five tacos can disappear faster than expected.
