Susan Ciminelli Day Spa

Decked out in Asian-inspired artwork with custom-built marble and granite, this very private, 6,000-square-foot spa features a full-service salon, locker rooms for both genders and two all-white Vichy rooms. Services include personal movement and stretching training ($80/hour), microcurrent treatments (a skin-firming procedure that stimulates facial muscle and rejuvenates the skin; $200) and reflexology ($140), which is often performed simultaneously with a facial. Celebrity clients include Martha Stewart and Ashanti.
