I had an above average foot massage experience at natureland.
My masseuse did a fairly good job. He was polite, professional and put in just the right amount of strength. But he did not press the right points like a proper foot reflexology. The seats were comfortable and clean but because it was a busy and hot day, the room did seem stuffy. Did not really feel the zen vibe which they are trying to create.
Their 60minute foot massage sessions cost $42 before GST. They seem to get a lot of clients so it would be wise to call before you go. Recommended if you plan to be in the area but certainly not the best one you can get in Singapore.
