The nail technicians at Bay’s Nail Spa pamper finger shingles with mani-pedis that take place in hardwood-floored salon with four cushioned pedicure chairs complete with footbaths. During a Shellac manicure, coats of the durable formula bathe under UV light so they have the strength to resist chipping even if struck by a folding chair during a thumb-wrestling match. The basic manicure instead layers fingernails with vibrant shades of classic polish, tinting freshly groomed and shaped digit tips with eye-catching color over the course of 35 minutes.

Clients lean back on padded head rests as they undergo the deluxe spa pedicure. A foot soak softens boot-fillers so that techs can more easily buff away calluses, and a bath in hydrating solution allows soles to absorb more moisture than a camel at an open bar. Patrons choose between lotion and an orange or mint sea-salt mask to relax leg termini from toe to heel, and after 45 minutes, feet walk away feeling refreshed and sporting sandal-savvy polish. Long, wavy mirrors dot lime-green walls inside the salon, where clients sip beverages and debate how many bottles of polish it would take to paint Lady Liberty’s toes.
