"There are a lot of great drinking towns in this world," says veteran traveler Anthony Bourdain. "For me, if I have a bar epiphany, it's usually about four o'clock in the afternoon, before the evening crowd comes in. It's usually the daytime guys sitting there, they know the bartender, maybe there's a jukebox, maybe there isn't. The sun's sort of getting low in the sky and coming in through the window, you've got the dust motes floating over the bar. It's what I call that sort of golden Tom Waits drinking hour." Here, five of his favorite stops.
