The Mansion London throw lavish parties with an elegant premise; taking place in "night houses" – secret Grade I venues – these parties are both over-the-top and relaxed affairs. For tonight, The Baron's Lady In Blue, Belinda, has taken over. With DJs, live shows, art, and performers at hand, there's plenty to entertain (besides the usual drinks and chatter) with the colourful guests of the night. General admission, includes a free shot on arrival. Details of the venue will be sent upon booking. Dress code: strictly blue (there's even a prize for best costume). Event ends 3am.
