Though their spa’s name might suggest otherwise, five is the most important number to the nail technicians at 620’s Nails & Spa. They focus on one hand or foot at a time, softening skin and grooming cuticles before brushing a glossy coat of standard or Shellac polish across all five nails. Along with their traditional manicures and pedicures, they apply CND Solar Nails during a two-step process similar to a French manicure. These chip-resistant coverings can last for up to three weeks without refills, much like a soda sipped once every seven hours. The spa doesn’t just specialize in nail services—a staff composed of aestheticians and massage therapists clears complexions with European facials and soothes muscles with Swedish and deep-tissue massages.
