Ikeda Spa (Bukit Timah)

The only day spa with a zen garden, it has become a favourite for its range of unique treatments like onsen baths (from $80, they have five treaments) in a Rotenburo hot tub, the Geisha Organic Facial ($240) which uses rice bran, camellia oil, and uguisu no fun (powdered nightingale droppings) – yes, you read that right – and a 300-stroke Japanese meridian massage technique, and the signature Ganbanyoku ($180), a Japanese detoxification ritual taking place on a special Ganbanyoku Stone Bed to purge toxins and calories as you perspire.
