ESPA runs the spa at the Ritz-Carlton in Pudong. It's not cheap, but for a high-end spa it's one of the nicest in town, not least because of its location. It's on the 49th floor above the ifc Mall and looks out over the skyscrapers of Pudong. It's got a space-aged aesthetic, rather than a balinese, buddha, incense vibe. Arrive at least 30 minutes before your treatment is due to start so you can use the sauna and the steamroom, and cool off by scooping handfuls of crushed ice out of the ice fountain. After your treatment, doze in one of the chair-beds by floor-to-ceiling windows. When you add in all the peripheries, you could easily spin a 60-minute massage into three hours at this place, and the staff aren't going to mind.
