The Iced Latte is another version of the Latte recipe in Good Coffee, Great Coffee. Like every other beverage, you won't be able to make the Iced Latte at the start of your playthrough. Instead, you'll need to unlock several ingredients as well as the regular Latte recipe before you can start taking Iced Latte orders. Iced Lattes can be less demanding than regular Lattes once you've unlocked Good Coffee, Great Coffee's Latte Art gameplay mechanic.
