This funky fast casual sets itself apart not just with its “Damn Good” tacos made with on-trend ingredients, but also for competing at breakfast with egg-filled options. Launching its first out-of-state location last year, it’s popular for its not-so-secret menu and taco of the month—with some proceeds going to a charitable cause. Past options have included a chicken-and-waffle taco and Asian-inspired tuk tuk tacos. The chain caters to dietary needs with vegetarian and gluten-free tacos, as well.
