I stumbled across this place when I was visiting Phoenix for a business trip. My intention was to find a Chipotle restaurant but I had found this place through Yelp. (There was a Chipotle a quarter mile down the road)
I decided to stop in and give this restaurant a chance. Don't judge it by the outside of the building or the lack of parking. The inside was pretty cool to see the drawings and wrestling masks on the wall. The dining area is small but all the customers there are willing to share a table during their busy time. I had eaten there during lunch time on Saturday. A lot of customers are in and out of there getting food which shows you that this place is popular.
I had ordered a standard burrito and also the rolled tacos with carne asada and everything on both. It was delicious and I did not have any complaints. If you are sensitive to spicy I suggest requesting the salsa on the side.
Overall, I recommend this place. You should give it a shot if you haven't tried it. It's not better than Chipotle. It's similar but has different flavor. If I am back in Phoenix I'll stop by again.
