Order the AZ Super Taco. This is hands down the best taco in AZ and one of the best tacos ever made!!! Their burritos are stuffed with potato so better to just order the tacos. Their fish tacos & ceviche are also top notch. Awesome salsa bar, plenty cucumber, except carrots are too hard.
Service is hit and miss but they always serve a quality taco in a reasonable amount of time. Inside seating and restrooms were completely remodeled last year and it's no longer a dive. You could take 99% of girls there without squirming. The sinks inside the restrooms are super cool.
I would normally give this place four stars if it was in Cali or Texas, but because it's literally the only good taco shop in the East Valley (Phoenix area), I have no choice but to give it five stars.
