I remember the first time I was confronted with a Jell-O shooter: Served in a little pleated paper cup, and brightly colored, it reminded me of the first polio vaccine. I thought then that the drinker's search for sensational weirdness had reached its end. But now, nearly needless to say, the Jell-O shooter has been eclipsed. Zubar, the hot new bar on Greenville, serves "candy shots," which we tried on a recent Friday night when the place was packed elbow-to-elbow with partying people shouting out their orders to the rare waitress or to Joe the bartender. Joe gave us three small glasses filled with beige liquid the consistency of milk of magnesia and gritty with ground-up candy: Mars bar, Snickers, and Reese's peanut-butter cups, mixed with vodka. I won't be ordering another round, but there was a barful of people to prove me wrong, and there's more to look forward to, according to Joe: He's working a Twinkies-flavored shot, as well as drinks infused with Slim Jims and Spam.
