A 1860-sq-metre, ultra-high-end spa with ice fountain and 'herbal cocoon room', and prices to match its Four Seasons location. Its signature treatment is jade-stone massage, but no matter what you book you'll get use of the spa's Jacuzzi, steam room and sauna – come in the morning or after 6pm if you want the Jacuzzi, because it's off-limits 2pm to 6pm.
