I honestly don't truly enjoy the taste of any alcohol except the sweeter stuff (certain liqueurs, flavored vodkas etc.). I have, however, acquired a taste for beer, vodka/7's (preferably GG or Belvedere -- I've found that there are fewer after-effects with them, and they have cleaner tastes to boot), or, if I'm at a higher-class establishment, cognac (Remy XO or, if I'm having certain desserts, Grand Marnier), scotch (single malt, preferably Glenlivet with a *touch* of water) or vodka martinis (one olive).
The only mixed drinks I truly
enjoy drinking are things like White Russians, Cosmos, Chocolate Martinis etc. (and no, I've never drank them in public -- I'm a guy after all

; I worked at a restaurant for many years, so I've sampled all manner of alcoholic beverage). Since I can't drink these at bars or lounges while maintaining a semblance of masculinity, I tend to stick to the standbys mentioned above.
But if you guys want to really taste some awesome shit (in the privacy of your own home or among friends who won't question whether or not you're an androgyne based on your choice of drink

), try these two on for size:
Peanut Butter and Jelly: Equal parts Frangelico and Chambord, chilled, served in a brandy snifter. Tastes
exactly like a PB&J sandwich.
Frangelico or "Cuarenta y Tres" (43) with milk on the rocks (very, very good)
EDIT: About the Long Island Iced Tea talk, the only time I've ever thrown up from alcohol (well, until two weekends ago -- I got
hammered without realizing it and later hurled a few times) it was a LI-T that put me over the top. We were out one night about 4 1/2 years ago and I was mixing drinks (bad move, but I didn't realize it at the time despite the common warnings about not doing so); this bartender makes me a LI-T with a shit-ton of tequila, and it did me in an hour later on the subway ride home. To this day, if I catch a whiff of tequila it triggers my gag reflex -- I consider this a blessing, since it'll keep that evil, evil spirit far away from me.
