Poppin' Your Cherry. You'll be disappointed.
I like Coke Zero, Vanilla Coke Zero, and diet Dr. Pepper. But I can't stand the cherry. I have also had A&W diet root beer. It was pretty good. But I have found that anything with the cherry flavor lacks real cherry flavor. It's not very good. Some things with vanilla flavor can be iffy. Sometimes the cherry or vanilla flavor actually tastes like soap. Yech!! I have also found that some diets don't taste like the real thing. I hope you can sell it to the kid so you're not stuck with it. Put some ice cream in it for him!
