Hi,
Maybe try Tan at Sihalath or Linda at ThipTawan, both in Bolton.
Sihalath is in the large basement of a bed shop. The rooms are large and it doesn't feel like a basement.
ThipTawan is on Tonge Moor Road in the centre of a block of shops. A bit of an odd layout but perfectly functional.
Tan is powerfully built and offers good massage. I believe extras are available.
Linda is much smaller and older but again offers a good massage and again, I believe extras.
Regards
Smithy
