Yeah, Sunday nights at the Unknown Theater have featured drop-ins by the likes of Jim Gaffigan, Neal Brennan, Brett Ernst, Chris Porter and Bryan Callen. And how cool is it that Bobby Lee is content to mingle without going up, while Bill Burr enjoys playing drums in the postshow musical jams? But here's the real kicker: $5 scores all the Bud and Bud Light you can pour down your gullet. Is it any wonder the 3 1/2-year-old weekly show attracts both regulars and after-work employees from the legit clubs? Not that 100 or so folks milling about in the cavernous, multimedia space is anything to sneeze at, but for Sean “Sax” Carr, who serves as Unknown's director of promotions, and whose Insiders of Comedy recently took over the evening, it's all about growth. “We don't exploit the comics or the audience. We don't do bringers; we don't have drink minimums. We just want everyone to hang out and have a good time.” 1110 Seward St., L.A. (323) 466-7781, unknowntheater.com.
