Dallas is famous for a lot of things, but one you may not be aware of is its claim to fame as the home of the frozen margarita! In 1971, Dallas inventor, entrepreneur and restaurateur Mariano Martinez invented the frozen margarita machine, adapting it from a soft-service ice cream machine. That first machine now sits in the Smithsonian National Museum of American History.

As a tip of the hat to this tasty and momentous accomplishment, VisitDallas has introduced its Margarita Mile, a self-guided tour of the most sought-after margaritas in the city. The convention and visitor bureau claims “no bottle of tequila” was “unturned” in the making of this margarita bucket list. The city’s “best and most brazen” margaritas have been curated into one colorful (and free!) app available on Apple Store and Google Play.
