You don't see many barber poles these days. But there are two of the iconic red, white and blue signs, lit-up and slowly spinning in front of Coachman Hair Styling on top of the hill on East Post Road. Men (and women, I suppose) who want to experience something like a classic, 20th century gentlemen's barber can do it here. Change the covers on the magazines and get rid of the modern electronic devices and this could be a location for a movie set in the Fifties. The fixtures and furnishings seem to be restored classics. The traditional menu of male grooming services is provided by a man who has years of experience and an expertise that is almost second nature. It is open Mondays; the shop accepts cash only.
