I haven't made a gingerbread house in years but I was entranced this afternoon by the Gingerbread City of more than 70 buildings created by architects and engineers and on display at the V&A until January 6. (If you can find it, badly signposted and tucked away on the 4th floor.) Mostly grown-ups there this afternoon and it wasn't crowded but as it's free for children, I think it's the best value Christmas outing in London. (£6 for accompanying adults.) I thought I'd drop in for half hour but there was so much intricate detail that I went round four times giggling over Polo mint bicycles and gingerbread apartment blocks  furnished with allsorts and a sugarloop high line. I'm inspired!
