Total dive. Cash only. No indoor seating.
BEST. MEXICAN. FOOD. IN. PHOENIX.
Firstly, it may be cash only but the prices are great. Just hit the freaking ATM before you go and stop whining. They have a huge menu, so large it takes up a good portion of one of the walls of the phone booth sized area you order from inside. The tortillas are so fresh they could easily go head to head with Carolina's. The red chili is by far the best I've ever had, as noted by some fellow yelpers. Don't miss their homemade taco sauce (I think they just call it hot sauce). You'll want to buy a quart to take home.
Don't let the exterior fool you. This place is top notch, with very friendly staff that will take good care of you. Stop by and take it home, if you can, but once you get a whiff of it, I challenge you not to pull over and devour it before you ever get on the freeway.
