Girlfriends describes itself as ''a professional nail and girlie boutique,'' with a personal philosophy this is ''a spontaneous, open, get-off-the-world for a while, belly-laughing getaway that's a cure for the soul.'' Stop in for a relaxing mani-pedi, or if you want to have a real girls' day out schedule a Girlfriend's Party and rent the whole salon for an afternoon of pampering.
