I know there was one last season in Calangute, i will try 2mrw and find out the name and if they are still doing it, my mate used them but only for filling in nails though.
My wife has used a couple in Calangute in recent years.
There is one at the Colonia De Braganza Hotel (probably wrong spelling) which is down the lane at the Red Lion pub. The other one is just across the road from the Red Lion pub, while she was there I was in the Red Lion pub.
