Despite the soap opera of the last few decades (multiple owners, loss of the World Series of Poker, a brief closure), Binion's is still a must-visit for the serious gambler, especially those who like their casinos dark, smoky, and full of a classic "Vegas, Baby!" vibe. A remodel a few years back took out a bunch of slot machines in an effort to improve flow, and some parts got painted, so it looks less dingy (but still like an Old West bordello), but otherwise it remains essentially the same. That includes the relatively high claustrophobia level. It offers single-deck blackjack and low minimums, 10-times odds on craps, and high progressive jackpots. Real gamblers still won't consider going anywhere else. 

Binion's was internationally known as the home of the World Series of Poker. "Nick the Greek" Dondolos first approached Benny Binion in 1949 with the idea for a high-stakes poker marathon between top players. Binion agreed, with the stipulation that the game be open to public viewing. The competition, between Dondolos and the legendary Johnny Moss, lasted 5 months, with breaks only for sleep. Moss ultimately won about $2 million. As Dondolos lost his last pot, he rose from his chair, bowed politely, and said, "Mr. Moss, I have to let you go."

In 1970, Binion decided to re-create the battle of poker giants, which evolved into the annual World Series of Poker. Johnny Moss won the first year and went on to snag the championship again in 1971 and 1974. Thomas "Amarillo Slim" Preston won the event in 1972 and popularized it on the talk-show circuit. In 2002, there were more than 7,595 entrants from over 22 countries, each ponying up the $10,000 entrance fee, and total winnings were in excess of $19 million (the tournament was also televised on ESPN). During one memorable year, the participants included actors Matt Damon and Edward Norton, fresh from Rounders, a movie in which they played a couple of card sharks. They decided to try out their newly acquired moves against the pros, who were unhappy that these kids were barging in on their action and so, rumor has it, offered a separate, large bounty to whichever player took them out. Both actors got knocked out on the first day but took it with good grace and apparently had a blast. Matt's buddy Ben Affleck, an experienced player, tried in 2003 -- the line on him to win (he didn't) was 400:1. Note: In 2005, the World Series of Poker moved to the Rio, under the auspices of Caesars Entertainment, which bought the rights to the event in 2004. The 2016 top prize was $8,005,310.
