Popular Dallas restaurateur Mariano Martinez—who runs three restaurant brands across the city—has a legendary claim to Tex-Mex fame: inventing the world’s first frozen margarita machine. The iconic creation even earned a spot in the Smithsonian Institution’s National Museum of American History in October 2005. To experience the famous frozen concoction for yourself, head to Mariano’s Hacienda. Don’t miss the Queso Mariano (queso topped with taco beef, tomatoes, guacamole, and sour cream), the Feast Fajitas with chicken, steak, and shrimp, or The Whole Enchilada—a massive 20-inch platter loaded with a chicken enchilada, guacamole tostada, beef taco, chicken taco, Tex-Mex rice, and beans.
