This unassuming Colfax spot serves up some of the most authentic Mexican street food in Denver, drawing lines that snake around the block on weekends. The carnitas are legendary – slow-cooked pork that falls apart at first bite, piled high on handmade corn tortillas. Their al pastor hits different too, with perfectly charred edges and that sweet-savory pineapple finish. The space is no-frills: fluorescent lighting, plastic chairs, and a counter where you order. But that's exactly the point. This is where Mexican families come for Sunday lunch and where night shift workers grab breakfast burritos at 7am. The salsa verde has serious heat, so pace yourself. Cash only, and they close when they run out of meat – which happens more often than you'd think. Worth the wait every single time.
