I believe this particular establishment to be the best restaurant in Arizona. I have felt this way for a while now and it's mostly because the "al pastor" is the most delicious and addictive taco or gordita around...or dish of any sort! The atmosphere is what you might expect from an authentic Mexican eatery: corny and comical, but the jukebox is solid and the Spanish soap operas are always entertaining as you wait for heaven to come to your table.
Also amazing here are the tacos de lengua, cabeza, and the soups are clean and flavorful. And the salsa bar is perfect with plenty of roasted jalepenos, escabeche and three different salsas all wonderfully distinct and properly seasoned.
