This is the kind of place you could drive by every day on your way to work and never notice. In fact, we'd passed it by numerous times without giving it a second thought, until one day, the light bulb went off over our head. And are we ever glad we popped in to this Sunnyslope outpost, just south of Let It Roll bowling alley (a Best of Phoenix favorite). It's cash-only, it's no-frills, it's dirt-cheap, and, if you're lucky, you may see an employee rend a cooked goat as you chow down on awesome Mexico City street food such as tacos, burritos, tortas, and huaraches. It's that authentic. In addition to the standard asada, jamon, chorizo, carnitas, and pastor, you can get pierna (pork leg), pata (pork feet), cabeza (cow's head), and suadero (rose meat). What's rose meat, you ask? It's the fatty top part of the beef, just below the skin — served up chopped and grilled on top of a huge huarache ($7 and big enough for two people). And it is delicious. Well, we guess the secret's out on El Rinconcito now. You can thank us later.
