i was there a good 10 years ago, and it was a 'legit' shop -- not so much as a friendly slip of the hand -- but it was a serious, strong massage, including walking on your back --
unlike any other places I've been to, the rooms sported handrails on the ceiling to maximize the back walking... and the tables had padded holes where your head rests, putting you in the optimal position for a massage..
also, as i recall, the woman was older and not as overtly sexy as is the standard...
lastly, i recall having a fair amount of time in the sauna, where i was face to face with other customers
nevertheless, it was a long time ago, and it may not be the same place or same type of place
