The Four-Star Mandara Spa is decorated in traditional Balinese style, with plenty of flowers, dark carved wood and mountains of colorful throw pillows. In the waiting area, there’s plenty of room to spread out with your cup of tea and the treatment menu or to Zen out to the New Age music that’s playing in the background. There are English-language magazines to flip through, including local city magazines like Time Out Shanghai. In addition to the reception desks, where you’ll check in for your treatment, there’s a display of Anantara spa products that are available for purchase. The rest of JW Marriott Hotel Shanghai at Tomorrow Square is bustling and light-filled, so the dark, soothing Mandara Spa is a welcome contrast.
