Christian Schneider, a hair stylist whose salon resembles a museum from the 1950s, is the person to go to for a distinctive haircut and refined conversation. It’s a place “for men and boys,” according to the sign at the door. Rock & roll music fills the basement, accompanied by the humming of a golden oldie refrigerator. The leather seats have been around since the dawn of time, and the bright blue moped begs to be taken for a spin. Customers get down to the rhythm of the rock & roll beat, and time travel has never been so lively.
