Butterbeer. It's sweet, like cream soda, butterscotch soda. The cream on top, like melted vanilla ice cream that's been whipped to barely soft peaks. I like it cold and frozen. I didn't get to have it hot sadly. It's perfect to grab and wander around the Wizarding World and get lost.
At the bottom of this post is the Pumpkin Juice which taste like a spiced apple cider and pumpkin spices. It was way too sweet for me.
