Fiery sauces, funky murals and Tex-Mex with equal doses of undergraduate reverence and irreverence.. In Short This Tex-Mex chain, started on the University of Florida campus, serves burritos in regular and hearty Tijuana size. Choose the stuffing: mildly-spiced ground beef, chicken, bean or a mix, wrapped with cheese, lettuce, tomatoes, onions, jalapenos and sour cream. For a lighter meal, try blackened chicken quesadillas. Sides of salsa and a hot-sauce bar dispensers with concoctions like Chickens**t, a fire and mustard combo and Thai sweet chili also are offered.
