In Cambodia there really is no Cambodia escort services and the reason is that you can talk to any taxi driver or motto driverin Phnom Penh or Siem Riep and they can take you to any number of different bars clubs massage parlors and discos where the women that are there for the most part are escorts in that they will go with you and provide the kind of services that you would expect a escort service to supply.
In Phnom Penh there are several what are called Freelancers bars that the guys that live there will go to when they need a emergency girlfriend The most famous being Sharkys followed closely by the Walkabout which is conveniently always open. The other place to check out where there are large numbers of freelancers would be Martinis which is a bit hard to find but worth the trip on most nights after 10pm.
Siem Reap which is the city that you stage from to go to Angkor wat has some spots but in Siem Reap the venues change quite often where the ladies of negotiable virtue can be found but go to the main section of town and the the women will find you or you can talk to the taxi and mot drivers and they will know for sure where the current hot spots are.;
Sihanoukville the other major tourist destination the place to go is the Freedom bar or go up on the hill. Sihanoukville use to have a couple of Chicken villages and they are still there but it is not like in the old days when there were literally hundreds of women that would just love to show you a good time. Your best bet might be to engage a Khmer Escort in Phnom Penh and bring her to the beach with you.
