Stoopen, who is from Mexico City, opened the restaurant at 12005 Hwy. 290 E, Austin, with his mother-in-law, Betty Gilmore, who has been working in restaurants for 20 years, he said.
Stoopen was living in Mexico City and working in public relations and customer service in 2019 when his wife’s mom said they should open a restaurant here in Austin.
“Everyone told us in Austin they love actual real Mexican food, not just Tex-Mex,” Stoopen said.
Stoopen said his staff focuses on making tacos and a few other menu items in a traditional style with fresh ingredients daily rather than an expansive menu with quicker recipes.
Stoopen said in Mexico, pastor is always cooked on a vertical spit called “el trompo,” but in Austin he has found many pastors heated with oil in a pan, which changes the consistency and flavor. Taco Margarita’s signature dish is tacos al pastor slow cooked in the traditional manner with over 20 ingredients for flavor and finished on the griddle without oil, Stoopen said.
