Don't do Hanoi, big no no, you wont get anything. HCMC is great, full on and whatever you want. Many ask prices in $, tell them your Uk and pay in Dong. Massage about VD300,000 - HJ the same and FS VD1,000,000 to 1,500.000. All very young and attractive. Freelancer clearly cheaper again, but HCMC doesn't come alive until after 2300.
