'FLASK Liquid Nitrogen Ice Cream' is a lab-themed ice cream parlor in Busan, South Korea, specializing in liquid nitrogen ice cream. Staff in this ice cream parlor sport white lab coats as they concoct delectable ice cream poured out of lab flasks and test tubes, freshly mixed and frozen using liquid nitrogen. Occasionally, a blowtorch is used in the preparation process.
There are four delicious flavors to choose from: Strawberries & Cream, Pure Milk Gelato, Creme Brulee and Mascapone Tiramisu. The Pure Milk Gelato is topped with droppers filled with fruity sauce, while the Mascapone Tiramisu is topped with a chocolate-filled syringe.
FLASK Liquid Nitrogen Ice Cream is open nine hours a day, but often sells out. Shockingly long lines are a regular fixture outside the "lab" doors, with a 30-minute wait time not unusual.
