Those who need the gambling equivalent of training wheels should look elsewhere: This is world-class poker play in an old-school atmosphere.

"The Bike," as it's known, ranks as one of the world's largest card casinos and is renowned for world-class poker tournaments like the "Legends of Poker." All 130,000 square feet of the green- and cream-colored interior are awash in marble and brass. The old-West atmosphere is heightened by the clatter of chips, wails of agony and screeches of ecstasy rising from more than 170 gambling tables dealing poker (including Texas Hold 'em and Omaha variations) and other games (including Pai Gow and Caribbean Stud). Toothpick-chomping, game face-wearing cutthroats roam around looking for their next victim. If you don't know who your table's sucker is after 20 minutes of playing, it's probably you. —Patrick Green
