You could get a less expensive manicure at any of the walk-in salons that line Newbury Street, but will it last a blissful, chip-free week? A manicure at Bella Santé will, and that, combined with the friendly service, exceptional cleanliness, and immaculate attention to detail (excess polish is erased with a tiny paintbrush), makes the service worth the (slightly higher) price. The staff here can create a flawless French manicure and recommend a regular maintenance program to keep nails strong and healthy. An added bonus: the extensive collection of O.P.I. and Essie polishes to keep you looking fashion-magazine fresh.
