If you are the sort of person for whom there is no such thing as too much chocolate, and for whom a sugar rush means elbowing your way through the throng to be the first to buy from or watch chocolatiers at work, then this year’s Chocolate Festival is probably already in your diary.

From 11am on Friday, 9th December until it closes at 6pm on Sunday, 11th December London’s South Bank will be full of people with sticky chocolate smears around the slightly crazed grins on their faces, ostensibly finding suitable gifts for others this Christmas. Any bets on how many will eat their purchases on the journey home?

With 40 or so exhibitors and 25 demonstrations, tutored tastings or talks (some of which are ticketed so hurry to book) it might just be possible to overdose on the hard, brown stuff.

You’ll find chocolate bars, brownies, cupcakes, pretzels, fudge, macaroons, cookies, churros, truffles, cocktails and beer in Southbank Centre Square, Belvedere Road, London, SE1 8XX – just behind the Festival Hall and down the stairs from the Hungerford Bridge.
