At 2:30 in the morning, this shredded beef taco would be a godsend ... A little scoop of juicy meat, so fatty and plump on your tongue, nestled between a perfectly-fried corn tortilla with some cheese, tomatoes and shredded lettuce. Two salsas: green tomatillo and red chile Japones. That is all you need for instant bliss! 

But despite its familiar late-night ambiance, Bernardo's Mexican Food is actually a breakfast and lunch place. Bernardo Acosta and his family from Magdalena, Sonora serve up a simple menu of green chile burritos, carne asada fries and combo plates with rice and beans. They've been here on this little downtown corner for 4 and a half years now, but for some reason, they're still under the radar. Why? 

Weird fact: Before it was Bernardo's, it used to be a Taco Shop. And before that, it was apparently a Chinese restaurant ...
