You start by ordering through one of their kiosks. I believe you can also order at the counter. The kiosk sneakily prompts you to tip (you’ll understand when you order), and there was a service fee added as well. Our drink, a Pineapple Jasmine Green Tea with Passionfruit, arrived in under 5 minutes, which was really speedy. The drink itself was satisfying, but not much different from other places.
