Los Tios Mexican Restaurants have been serving Houston authentic Tex-Mex for almost 5 decades. In that time, devoted diners have made Los Tios a family tradition handed down over generations. Favorite tables, favorite waiters and most importantly favorite dishes have become rituals with Houstonians who have named Los Tios “Houston’s Best Tex-Mex” time and again. Los Tios offers Tex-Mex favorites that include fajitas, enchiladas, tacos, nachos, tamales, burritos, quesadillas and our famous puffy shells dripping in creamy chile con queso. Many Houstonians got their first taste of a frozen margarita at Los Tios as we introduced Houston’s first frozen margaritas back in 1975.
