Tried Barq's yet? One of their old lines was, "Barq's has bite!"

Be aware. Barq's has caffeine. Or did. I haven't had any recently.

Might be where the bite comes from.

I have and always will swear by Diet Pepsi. I've been addicted to the stuff since I was 14!

I really like caffiene free Diet Pepsi and have been able to find it in some restaurants, like Panera Bread. If you are looking for caffiene free diet soda in restaurants, Chik-Fil-A has Caffiene free Diet Coke. Those are the only two that I know of off hand.

I really like diet Sierra Mist too - much better than any other diet clear soda.

Not root beer, my dear, Ginger Beer. Kind of like Ginger Ale, if it had balls.

It's rather unique stuff.
