El Norteño is a family tradition, at least in my family. My parents started eating here in 80s and passed down the obsession to me and my siblings. Very delicious!
I always order one of two things. Green Burro Grande or Machaca plate. Chips & Salsa always. I take the pint of salsa home and keep it in the fridge for eggs, chicken and whatever else would taste good with salsa.
If you're not uptight or whatever then you'll love this place. Don't judge a book by its cover! Don't forget that you're in Phoenix and embrace the delicious Mexican food!
