It's almost last call at the Dume Room, the bad boy (and girl) bar in here in Malibu. Just five days left, and it shows. Hundreds of bottles of booze, beer and mixers have dwindled to a few dozen. What you're drinking depends on what's left. The photos are gone, the plumbing's out and the juke box is on the fritz. Regulars crowd the pool table and huddle around the bar, taking a stab at making merry and failing. At 8 p.m., the place was almost empty. A few hours later, crowded but just as quiet, a smoky wake with a no-host bar.
