If ever you need a taco fix at midnight, keep La Tapatia in mind. With five locations spread across Houston, La Tapatia is one of the city's few 24-hour Tex-Mex joints. Popular for their beef fajitas and margaritas, La Tapatia offers entrees and drinks at reasonable prices (entrees all under $10) and with very generous portion sizes. Their usually busy atmosphere speaks to the city's love for the La Tapatia chain. So take your friends, family, or stop by after a night on the town for some late-night Tex-Mex cuisine.
