Cool off with a margarita this summer and help pick the best one in Dallas.
Driving the booze: 16 restaurants and bars are participating in Visit Dallas' Margarita Mile Cup, which kicked off this week and continues through July.
The big picture: World Cup visitors and North Texans can participate in the bracket-style competition.
"We want to give visitors an experience that's interactive, undeniably Dallas, and one that they'll remember long after they return home," Visit Dallas chief marketing officer Jennifer Walker said in a statement.
How it works: Save a free digital pass on your phone, visit participating locations and rank their drinks — collecting points along the way.
Rewards include a keychain worth 200 points and a travel sweepstakes entry worth 500 points.
Zoom in: Billy Can Can's Sonora Showdown, El Fenix's Match Day Margarita and SĒR Steak + Spirits' The Golden Boot are among the contenders.
Fun fact: Dallas restauranteur Mariano Martinez adapted a soft serve ice cream machine in the 1970s to create the world's first known frozen margarita machine.
The machine is now on display at the Smithsonian National Museum of American History.
