I went to this place back in April. Very attractive girls working there when I went. The first time and second time I went I saw a small petite girl called Dear (I think). She did HR for £20, and was prepared to take top off, but I didn't bother with that.
The third time I went I saw a girl called (again I think) Sensa. Very attractive and very good massage but definitely no extras on offer.
So, that was 6 months ago, and it may be a matter of luck as to whether the lady you see is prepared to offer more that the standard massage.
