My friend's Dad would always use to say, "The best wine is grape juice, the best beer is root beer, and the best coffee is hot chocolate." Why anyone tries to convince themselves that the alcoholic swill they drink is anything better than non-alcoholic beverages, I will never know.
My favorite soft drink has been and always will be Coca Cola. Pepsi is a sad, sub-par imitation of it, and I'd rather get diabetes than cancer from the artificial sweeteners in diet.
