Last Wednesday, I attended the Burlington Arcade Christmas lights switch on. My friend and I sipped champagne, munched yummy canapes and marveled at circus performers. We ran away from the snakes and got excited in Lulu Guinness. We sampled macaroons in Laduree. We laughed as David Mitchell switched on the lights and couldn't quite believe that two elderly men were wearing tiaras without irony. A wonderful evening which prepared us for 'the start of retail christmas' (in Mitchell's words).
