Azteca's, on Richmond near Montrose, is an interesting blend of cantina and sports bar, with TVs competing with loud music and shouting people. The place specializes in drinks - happy hour is a big deal here - but it also has a large and varied menu. Its chunky, oniony salsa and flour tortillas are noteworthy. You will find not only the standard Tex-Mex offerings here but also legendary fish tacos, an excellent pork tenderloin stuffed with olives, jalapeños and cheese, and a delicious grilled red snapper served in a garlic white-wine sauce. There's also a good selection of vegetarian dishes.
