You may be lured in by the healthier Tex-Mex options such as fresh-made guacamole and shrimp ceviche, but you’ll find it tough to say no to the decadent Matamoros dip (chile con queso with ground beef, guac and sour cream) and the tampiqueña plate (steak fajitas and a fat cheese enchilada). Still trying to be good? Try the vegetarian-friendly ratatouille tacos.
