In Saks Fifth Avenue’s downstairs concourse, just inside the entrance door on 50th Street, is a special elevator that goes only down to the concourse under the main floor. The concourse houses beauty products, hair and nail and makeup salons. Go right past Natalie as you get out of the elevator, turn left and say merrily that you are going “back to see Vincent” (their star hairdresser) and quickly turn to the right. You will be in a divine little bathroom with two slots.
It’s very private, little used and clean and bright.
When you come out you can browse right on the main floor of Saks at Vuitton and let your mouth water at will.
