There's a Schlitz beer poster with a photo of a caballero in a huge sombrero astride his horse hanging above La Fiesta's front door. (When was the last time you saw a Schlitz ad?) And then there's a mural of a Mexican village on the back wall. The original La Fiesta at Katy Freeway and Bunker Hill Road is one of those Tex-Mex time capsules that are fast disappearing. The little 30-table joint opened in 1972, right around the time that Houstonians discovered a new drink sensation, frozen margaritas. A year later, sizzling fajitas became the rage. As a result, La Fiesta's menu straddles two eras. There are plenty of Tex-Mex combination plates, and old-fashioned favorites like chalupas and tostadas, and then there's the "modern style" menu items such as sizzling fajitas and frozen margaritas. After 35 years of practice, La Fiesta does it all incredibly well, and at unbelievably cheap prices.
