The IGUAZU DAY SPA's Amazon-inspired treatments have the power to transport people from the busy streets of New York City to a serene tropical rainforest. Iguazu's Bamboo Massage features bamboo shoots of different sizes soaked in essential oils, which are used to roll, tap and knead away any stress. Gentle strokes, shiatsu acupressure and friction help relieve muscle tension. "It's a really unique feeling," says Fabien Azoulay, owner of Iguazu. "Something about the shape of the bamboo gives this incredible feeling that people love." —R.A.
