Chill out in a Zen sanctuary that uses locally grown ingredients in autumnal body scrubs, herbal poultice massages, and coffee-and-cocoa slimming treatments inspired by in-hotel chefs Jody Adams (Rialto) and Peter Davis (Henrietta’s Table). The Spa for Humanity program donates 5 percent of spa package proceeds to one of four local charities, including MSPCA and EcoLogic Development Fund.
