Tenoverten
With four NYC locations each boasting a different vibe (Soho for modern-rustic, FiDi for industrial chic, etc.), Tenoverten makes it easy to indulge in a spa-quality mani, wherever you are in the city. We seriously recommend booking a pedicure while you're at it, but clear your schedule - these folks take their time (though the results are worth it).
