I visited the Euston Road place today, Ruen Thai massage.
Youngish to mid 20,s lady, very slim, in t shirt and leggings.
Massage room is ok, quite cramped but with proper table (hole for head)
Totally legit, was asked to undress and leave bottoms on.
Massage was excellent, very professional and enjoyable.
Absolutely no sign that anything extra would be offered, apart from coffee or a soft drink.
Well worth £35 for the massage, but i would be shocked if this was ever anything but a totally legit massage establishment.
