I couldn't finish my cup of LeFou's Brew. The first few sips made me think "WTF," then I was like "it's frozen apple juice," and then as I got closer to the end the foam got in there more and into the trash can it went.
Butterbeer didn't make me wonder about what I was drinking the first time; it's a butterscotch cream soda and there's not much more to it.
