I've been here twice.
The massage rooms are directly off the main reception and you're massaged on a matt on the floor. It's pretty clear this is a legit place, pants are kept on throughout and there's no hint of anything extra on offer.
However, on the second visit I was massaged by a fairly fit girl, early 30s, and I detected a little bit of flirting from her, and when I paid at the end there was that weird vibe from her. She knew I was single - I'd told her after she asked me the question...! - and I wondered if I'd given her my number whether there could have been a meet later.
But I wouldn't return here looking for extras, fairly sure they're no on the cards.
