Not sure if you're Vietnamese or not but I've got a number for a hit and run joint in HCMC D.14
The going rate is VND1.3M (roughy AUD$85) for a 1 shot session.
There was a lineup of about 10 ladies when I was back there in March of this year.
I normally tip the papasan 200k and he would pick out the best girl of the lineup.
I prefer a girl that gives me amazing service over a hot starfish.
Message me if you want the number, better if you can speak Vietnamese because they're very reluctant to service foreigners as prostitution is illegal.
