We all have our favorite manicurists, but Sweet Life Nail Bar and Lounge has an edge, a gentle one, that just might change your mind. It starts with the toxin-free, long-lasting, many-colored Zoya products that owner Diane Bilello insists on using, which leaves the Stapleton salon virtually odorless, a novelty in and of itself. But then sink back on this: Sweet Life's lounge-like atmosphere, replete with overstuffed armchairs and warm lamplight instead of fluorescent bulbs, takes the hurry and stress out of having your nails done, especially when you throw in a glass of wine, mimosa or Grey Goose martini from the bar. A bar? In a nail salon? Say no more. Mind changed.
