Coca-Cola, no contest. Though it's not like I hate Pepsi, or any of the others. I just vastly prefer Coke. I still find it kinda funny that it's named after the two drugs that were originally in it. Even though it's not in the poll, I would put RC as my second favorite (Royal Cola).
I like Coke from a can, and Pepsi on ice. Sprite/ 7up is nasty, I like Dr Pepper on a good summer day and Ginger Ale when Im sick
Definitely Coca-Cola. I used to drink a whole 2-liter of it every day, but I cut way down....I'll still have atleast one 20 oz. bottle every other day though. If Coca-Cola was an illegal substance, I would be the most notorious "drug" dealer in my city.
Ginger ale. In particular Canada Dry (schweppes is nasty). Also, there is (or at least was) a place in the Mall of America that made it's own ginger ale which was really good. NZ ginger ale is good too... nice and strong and not watered down!
Dr Pepper is what I run on and when I can't get it than I settle for Coke classic. Tried drinking diet soda a few years ago, well I had a werid allergic reaction to it and that ended my diet soda days.
