Another classic of the genre. G2O began life as Giuliano Spa for Beauty & Wellness way back in 1994, then went through several iterations before landing at its current, incomparable space. Housed inside two conjoined historic brownstones renovated to the highest “green” standards, G2O is the place for a daylong spa experience. For starters, there’s the penthouse lounge and fireplace lounge, as well as a skylighted hot tub. But the cutting-edge treatments are G20’s signature, from the LED light therapy to the hyperpigmentation facials to the detoxifyng herbal wrap. There’s even a separate hair salon to tend to your highlighting and Keratin needs.
