Countless diners have been able to enjoy Luis Dominguez's work during his 20 years in the Dallas restaurant industry in a career that spanned restaurants in nearly every neighborhood in town: Tillman's, Hattie's, Smoke, Chicken Scratch and, most recently, HG Sply Co. Dominguez helped create some of Smoke's most popular dishes, adding Southwestern spice and Mexican tradition to chef Tim Byres' barbecue. Dominguez died of COVID-19 July 22.
