It's not difficult to find vibrant nightlife in Cambodia, particularly in heavily visited destinations such as Phnom Penh and Siem Reap (which neighbours the Angkor Temple Complex). Bars and restaurants are plentiful, ranging from down-and-dirty drinking holes to smart cocktail bars. Outright nightclubs are few and far between, although girlie bars are anything but rare. Be sure to check a venue out before handing over a cover charge, as you may end up in a seedy environment. In Phonm Penh you can’t go wrong with the bars in the restaurants on the riverfront, which offer laidback family atmospheres.
Most major hotels offer entertainment of their own, with properties in Siem Reap especially good at hosting traditional dance performances during high season. Gambling is a major pastime in Cambodia and there are several casinos in Sihanoukville and on the border with Thailand. This same beach town is also a raucous backpacker haven. Steer clear of Victory Hill, unless you enjoy an up all night go-go dancing atmosphere (reminiscent of Khao San Road, Bangkok).
