The Liquid Nitrogen Margarita has been a staple at Beto & Son since it opened in 2016, and over the years, it's been a must-try for Dallas residents and visitors alike. Made with Avion reposado tequila, lime juice, agave, DeKuyper 03 and encapsulated fruit pearls, this margarita is designed to stay cold and slushy during hot temperatures. It's best slurped through a boba straw, which will allow for the pearls to travel through. The pearls provide quick bursts of sweetness to balance out the cold, boozy taste.
