Food Network On Demand has a Good Eats special concerning cocktails, looks like it started a few days ago. Alton goes over making 3 basic drinks, including a Martini, as well as some do's and don'ts when collecting home bar equipment. Was helpful to me, as I don't have a jigger/pony measure and I often overdo the spirits when mixing at home.
In a club or at parties I'll usually go with a gin and tonic if someone's asking for drink orders. Most parties I attend, there's usually an organic gin (the name eludes me right now, but I think there's only 1 organic gin being made, so that's the one) so I'll have that with a sparkling high mineral content water and a couple drops of flavored liquid stevia - whatever flavors are available at the party. When no one's looking I raise my pinky and enjoy my drink foo-foo style.
If, god forbid, I'm stuck with the almighty Beefeater gin, I'll have that with water or tonic and any type of flavoring. I appreciate this gin for its no-frills taste, but I'm usually not in the mood to drink it. I'm a man, but damnit, I'm not a caveman! But I do want to get drunk. So gimme Beefeater if that's all you got.
Left to my own devices, I'll go for Bombay Sapphire with any sparkling mineral water, over ice in a highball glass. I think the drink is officially called a Hanna.
My girlfriend laughs at me as she always and only drinks Budweiser.
