141 buildings and websites
[QUOTE=Midwestern;1987784]For example, I see discussions on 141 girls, but not about where they are or how to contact them.
.[/QUOTE]A previous poster mentioned two or three of the popular websites, which offer English versions. Miss 148 dotcom worked; the other is a dodgy link. So hit that website and you will see a few buildings, including a couple on the same major street as the Eaton, at 717 Nathan Rd. , 561 Nathan (south of Dundas); in Mong Kok there's 311 Portland and the King Hing Building (just Google it). There's plenty on the web, and on this forum, about the general procedure. You figure out which floors have the providers and it will be pretty apparent that the trade is being plied. (Christmas lights around the doorways, etc.) Apparently it is uncouth to knock, and there are various methods to indicate that the WG is otherwise indisposed.
I have not been to these places, but they are just a few of many. (I am loath to present myself as an expert on 141's; I worked for a year and lived about two blocks from the Fuji Building in Causeway Bay and never tried it. Regrets, I've got a few.) As warned over and over here, the photos you see on the web may or may not be the actual provider, or may be heavily photoshopped. At any rate, if you're willing to hoof it around, there are all sorts of places, say on Portland Street, and then there's the Temple Street Market. It's all walkable. Good luck.
