Bartender's choice: Rock 'n' Roll Trivia. R&R at the Twilight Room on Southeast Powell Boulevard means Rock 'n' Roll Trivia on Mondays (7 pm). When the clock strikes the bewitching hour, the Skynyrd is yanked off the jukebox and a reverential hush falls over the smoky lounge. "Put your rock 'n' roll brains on," says the bartender. And you'll need 'em, because they'll ask some far-out shit. Oh yeah, and the drinks are good and stiff, too. HAPPY HOUR, FOOD/DRINK SPECIALS, LIVE MUSIC, VIDEO POKER, GAMES, JUKEBOX. (CM)
