I am a Coca Cola fan, and I can tell if Im being served Pepsi by mistake. Some restaurants wont tell you unless you ask, and I always ask.
I like Coca Cola ice cold, and poured over lots of ice. It burns when it goes down, and really quenches my thirst. Its not too sweet, and goes with any kind of meal.
I dont drink soft drinks very often because of the sugar, but for a treat, its always Coca Cola for me.
I also like some of the interesting advertising that Coca Cola has come up with, particularly the ones with the polar bears.
