Ever wanted to look as immaculately put together as a 1940s screen siren, or as pristinely coiffed as a Betty Draper? The Powder Room is a gloriously retro hair and beauty salon that specialises in preening like its 1949. The £20 updo service is a great little bit of indulgence to get you ready for a special occasion- the cute little parlour on chocolate box pretty Columbia Road is adept at hair rolls and pin curls. There's also eyebrow shaping, manicures and £60 classes to teach you how to achieve the Powder Girls' big screen ready hair and make up tricks at home. Look out for top notch £5 bellinis served from teacups, and a fun sounding group pampering session which is ideal for hen dos.
