Get the concierge to write you the addresses on separate cards for the following:
Holiday Inn Lido (go to the Pig and Whistle Bar about 8:30 or so to start)
Suzi Wong's .. many girls there, sitting together, (upscale, not hookers... but if you are able to start a conversation... you can probably leave with one)
Goose and Duck (you can walk across the street from Suzi Wongs) It is an expat place, but the girls there are hit and miss.. some night several, some night none...
Maggies (upscale nightclub.. lot of Mongo's... some girls there just work the bar, for drinks and wont go with you, so ask)
Hollywood ( you can walk from Maggies, or take the cab...) Disco, many girls...
Hard Rock... (girls get there about 10-30 to 11... easy picking, need to negotiate the price)...
Street walkers in front of the HRC... go out, and stroll to the right... and if nothing back to the left. Hilton and Kempinski is down to the right, and Sheraton to the left.. so they work that area...
And remember to have a card to get back to you hotel..
You can then move from wherever you want.. place to place...
There is a "sauna" that offers full service.. but the few times I have been there have been a disappointment compared to the ones in Shanghai.
happy hunting
