Rows of shady trees shelter guests as they pass Nu Yu Day Spa’s brick façade, a sturdy shell that conceals nearly 1,000 square feet of soft, pamper-ready space. When guests open the green front door, soothing music wafts by as a friendly hostess greets them with a cup of herbal tea. Separated by french doors, private treatment rooms welcome guests with plush pedicure couches and pillowed manicure stations. In addition to nail services, techs shoo away stressors with massages, facials, and waxing treatments. Because Nu Yu's experts laud the health benefits of human touch, their services incorporate natural oils, salts, butters, and scrubs, which are applied without the use of sponges or robot hands.
