A Dallas institution since 1983, this charmer—with its lively murals and even livelier mariachi musicians—is still a nightly party. Bring a group if you can, because you'll feel less self-conscious if you get up to dance that way, and bring an appetite, too, because portions are ginormous. Though the menu does have some unexpected twists (goat, anyone?), you'll do better ordering such standards as enchiladas suisas or the tacos al pastor . Beware the margaritas, which seem innocent but pack a punch.
