Don't get too excited, 'Patron' doesn't mean that they make their margaritas with Patron tequila; it's just the name of the place. They claim to serve "authentic" mexican food, just like a lot of other places that really don't.
As mexican restaurants go, Patron Azteca is one of the nicer ones. They have a bar and a big dining room, some booths and tables. There's mexican music playing with spanish lyrics. It definitely feels like a Mexican restaurant.
They gave me a big basket of chips and a big tub of salsa with some beans and cheese for dipping. The chips were good, and the salsa was very good and was obviously freshly made.
My server made a couple of visits and then disappeared for quite a while; you're better off if you order quickly it appears. When she did return, I ordered the chili colorado, which is described as braised beef with tomatoes and onions. The food was brought out almost instantaneously on a very hot plate; I suspect a microwave was involved.
After the good chips, I expected something a lot better than this. The salsa looked old (or maybe microwaved?) and the rice was pedestrian. The beef itself has no spice at all; it reminded me of beef stew. It wasn't awful and served up a portion of protein, but It wasn't what I was hoping to get at an "authentic' mexican restaurant.
They have $3 "lunch" margaritas and they do the Taco Tuesday at the bar thing.
It took way too long to get my check; the servers don't flow here properly. But not a bad deal overall for $10.
