Piccadily Hanley, there are 2 in very close proximity, the obvious shop front of Natural Healing on the corner of Piccadilly, this is completely hit and miss, girls change around rapidly , so its pot luck to what happens and what you get, can be the best service you ever had or the worst.
Almost within reaching distance from that shop is Chinese Health on Cheapside, its pretty low key regarding advertising etc. It's Grace/ Lilly who has been around for ages, previously in Newcastle town center- again what's on offer will vary as to how well she knows you and regular customers will get the best of her.
Bridge Street , Newcastle, Crystal Wellness- it was rubbish when i went, poor service and ridiculous prices, but again would have no doubt that it will be completely hit and miss
