There are many worse injustices in the world, but chief among the lessor wrongs I'm aware of is that at the time of this writing, the original Los Dos Molinas is rated only 3.5 on Yelp. This is an insult to the integrity of Yelp's rating system. In the reviews there are complaints that the food is too spicy (yes, in fact it's very very spicy, so beware), the service can be slow sometimes (they are very popular and very busy - but my service has never been slow), the food is tasteless (are you kidding?? It's easily some of the most flavorful food I've ever eaten), and the décor is cheesy (yes it is.) If spicy food and cheesy décor is not your thing, then don't go. If you can deal with that, then visit Los Dos Molinas and you'll be in for a treat possibly unlike anything you've ever tasted.
This location is basically a national landmark, located in the former ranch home of Tom Mix. If you don't know Tom Mix, he was a silent movie star - basically he was John Wayne before John Wayne was John Wayne. There is an outdoor courtyard where you can sit and drink while waiting for a table in the smallish dining room. The dining room is somewhat dark and full of kitschy décor, but this doesn't impact the quality of the food.
I highly recommend beginning your meal with a bowl of green chile stew and a savory sopapilla - wow, so good. I've eaten at this restaurant on regular visits to Phoenix over the past 30 years (my first Yelp picture of Los Dos Molinas is dated 2013) and it's consistently been delicious whether I've had the enchiladas, the pork roast, or anything else on the menu. Everything they serve is spicy, but pay special attention to the chile symbols on the menu as they designate the items that are EXTRA spicy. As the chef says right on the menu, he doesn't know how to make mild.
Los Dos Molinas is my favorite Mexican / New Mexican restaurant - I lived in Houston / San Antonio for 10 years and Oklahoma for 7, so I have a pretty good idea what Mexican food is supposed to taste like. If you can handle spicy food, I'm confident you'll like it too.
