I agree with you on that one! I've been drinking those like mad this winter..
But my all time favorite is obviously Long Island Iced Tea!
More to come when i had some sleep..
I really like Cuba Libre especially when mixed with Havana Club 7 anos, but recently I used Captain Morgen Spiced Gold quite often so it isn't a Cuba Libre in the traditional sense anymore but still very tasty.
I also enjoy a White Russian or a Mojito ... and Long Island Iced Tea espacially if I want to get drunk.
