Phnom Penh was the best kept secret in South East Asia in the early 2000's.
It was a wild 24-hour party town, bars with young, pretty and non-pushy staff, cheap as chips, loads of cool places to drink and eat at all hours.
Sharkys, Pickled Parrot on 104, 1Zero4, Colonial Bar, Zanzibar, Rose Bar, Zapatas, Walkabout, Howies, Shanghai, White Cobra, Heart of Darkness, Candy Bar, etc
Great memories but changed days now, unfortunately.
