My "home" ground those year is Prince Health Center at Cecil Street, smack right in the CBD area, basement with 2 storey.....
Marina South Dragon if you in that era, should heard about the HIV case, that's when they go down thrend even way before Marina South was engalve by the barrage.....
Those era, within famous hotel sure got a HC, some hotel even have this "room service", they secure a few rooms within the hotel and we pay more to use the room for massage services, very the safe
Still many more, most memorable one should be the ex Winsor hotel, full "old" facility only $20 entrance fee with a 45 min massage with "granny", and HJ only $5, whahaha, really a budget place, the whole HC was damn run down
