Massage/Spa recommendations in Newy?

GF's birthday is coming up, and I'd like to treat her to a nice massage/pampering session for both of us. We've had one tandem massage in Sydney previously, probably 2 years ago, and we always said we'd do it again because we both loved it - but we never did.

So, where in Newy do you guys here recommend for such a massage? Ideally somewhere we can both be seen at the same time, or in tandem. I see there are plenty with good ratings, but I have learned to be very distrusting of google reviews.

Cheers!
