Wow. A lot of people seem to like Coke as a mixer. I don't understand why people like it as a mixer, perhaps they never tried anything else?
As for me I don't really have a favourite drink. But I do like:
Spirits: Captian Morgan's, Jagermeister, Jamesons, Havana Club. (All straight)
Beers/Ales: Becks, Tiger, Duvel, Smithwicks, Guinness, Erdinger.
Cider: Bulmers/Magners. (They're the same thing, different names depending on where you're from.)
