Time Out says
Gretta Monahan might be our city’s first lifestyle guru, a woman able to speak comprehensively about style and diet as well as beauty and travel. Located inside the Westin just a stone’s throw from the chichi Copley Place mall, Grettacole is a full-service operation, from waxing to hair extensions to reflexology. But its calling card is the Darphin 3D facial menu: customized treatments incorporating the luxe Parisian line for your most glowing visage.
