El Fenix, Celebrating 100 Years, Will Debut New Margarita Made With Our Favorite Hipster Mixer

El Fenix may be turning 100 this year in Dallas, but boy, has the restaurant stayed current. In August 2018, as part of its year-long centenarian fiesta, all El Fenix restaurants will debut a new margarita featuring Topo Chico and a chile-lime rim made with the Mexican seasoning Tajín.
