Well - i live in sheung shui, and its pretty easy, plenty of pink neons on virtually every street
might want to avoid san fat street where there is a cluster if you are a bit shy, its on a well lit street with several eateries and a minibus stop thats always busy. recommend that you walk down san shing avenue where there are several.
The 141 walk ups are a bit hit or miss - price is $350 standard, most girls are from the mainland.
nb be warned the apartments are generally quite grotty, but the girls that i found are about average, to ok looking, typically up to 30 (look younger)
BUT my own personally worst attempted punt was on sunday just past.
spent the best part of 3 hours walking around Sham Shui Po, Prince Edward, Mongkok checking neons and calling numbers to no answer, all to busy doors
Finally walked back to a sauna in MK on Nathan road that i was at last week and the service was great!
The reason being that on a sunday evening at about 5-9 was when all the hk hubbys and guys down from china are getting their punts in before going home to wives and families and the working world on a monday....
In Sheung Shui i would recommend that you try out the massage parlours, they are everywhere! (anything with a light on after 6pm is game) they are all pretty much the same, I've tried several and yet to end up with a veggie
most are pretty nice inside / renovated and have 2-3 girls working
standard pricing is 170 for massage and 100 for HJ finish
although i've had several freebies of FS and BJ's - go try your hand
if you want specific ones let me know, ciao KM
