I'm a little confused by the low ratings. If you're from Scottsdale, heck, if you're from Arizona, Sonoran Mexican food is what we know. This place is a staple.
You don't like a lot of cheese? Go to a Mexican-fusion place that's popping up with organic micro greens. This is the real deal. There is lard, there is calories, there is FLAVOR.
Why 4 instead of 5 stars? This place hasn't been renovated in years, not a bad thing, but it's truly showing it's wear.
