Unlike Galfordo, I've been fortunate to live in places with a reasonable night life (LA, which is one of the better places in the US; and Minneapolis, which has been improving by leaps and bounds in the past two years). I never drink before I go out. I only drink where the party's at. Personal choice, I guess: I don't like the implication.
When I go out I usually skip beer (too filling). I also don't enjoy wine (for some reason it makes me burn up, and I don't like sweating when I drink). My drinks of choice usually involve Vodka or rum.
I like straight vodka, chilled. I like most vodkas: Stoli, Skyy (Skyy Berry + Fresh Squezed OJ = one great screwdriver), Grey Goose, Smirnoff, Absolut, etc. I hate potato vodka.
I used to drink a lot of drinks with Tequila, but I've passed on it since its a little too rough (unless you go really top shelf, which I'm not).
Rum is becoming another favorite of mine, I love mojitos -but only when mixed right (so you can't taste anything too boozy or too sweet). The mojito is a little more difficult drink than most realize, IMO.
I hate gin martinis.
I found that top-shelf single-malt scotch is unbelievable good, but I'm never forking over $28 for a shot again (though the scotch was older than me).
I enjoy some of the new wave of blended liquers: Hpnotic is my current favorite.
Bailey's is a fine liquer as well (I guess it would be considered one)
If I'm in no particular mood I'll usually go with a screwdriver, Cape Cod, Long Island Ice Tea, or the special the place makes. I'm also not opposed to most "girly" drinks either -heck, if I'm getting loaded I'd better like what I taste.
