Been to two in the past year. Both NOT recommended.
St Marys Brothel, near the ink shop very close to great Western Highway. Website just full of fake photos so don't bother. When I went saw a viet milf probably around 50 yrs old, very tired and worn out. Paid $150 for 30mins.

Second one was a Chinese massage shop corner belar St. Another Chinese milf in a dirty ass joint.

Best punt in the area is saigon princess tbh, even tho you won't get fs.
