If you enjoyed Barcode then you'll probably really enjoy the drag show at Blue Chili in Phnom Penh. They moved to a bigger location and is more like a club now but the drag show is excellent. The only downside is that, like Barcode, it attracts a lot of straights and women.
Spacehair Bar had a lot of nice eye candy but, alas, all were straight gym bunnies. But still is an enjoyable place.
The new Toolbox pub was fun. A nice mix of twinks and cute gym-fit guys - all gay apparently. Also quite a few freelancers hang around there. Best of all - no women anywhere unlike the other bars in PP.
The Phnom Penh version of DJ Station is called Heart of Darkness. Go after midnight on Friday or Saturday night and it will be packed with cute gay guys. Quiet any other time. Just don't drink the alcohol.
Lots of nice boy massages in the Russian Market area. Chanak, Boran, Ah Ram, Aroma, Ganesh. All within a ten minute walk from each other. All have nice facilities like aircon and toilet/shower in each room. The boys are all behind glass wearing a number, like the gogos in Bangkok. Pick the boy and away you go. Going rate is $10 for an oil massage. Expected tip is in the $20 to $30 range.
Enjoy PP. I certainly did.
