When I first tried one of the houses at jalan molek the selection was quite limited at the time with only 3 girls to choose from and I believe they are all Thais with lots of tattoos covering their skin. Service wise, it was pretty standard, but for the amount, I wouldn't expect anything more.
In the future, I hope to see more girls available and the OKTS become more willing to inform customers of the wait time as of now most of the OKTS are quite tame unlike in the olden days when they would drag you inside
As of right now, most of the houses near Westerhout Rd are either closed or fully booked. There isn't much information gathered from the OKTs either, so it is difficult to decide whether to wait.
