Best Udon in London, with an exceptional specials board. The head chef Shuko Oda opened the first restaurant in Soho 11 years ago, and they now have restaurants in the City and on Broadway market. Great for kids, our son loves the Mackerel udon.
It's a members-only library but you might be granted access with a research request. The writer's room is great but there's a few special, hidden corners among the bookshelves to tuck yourself away in.
The Hayward Gallery in Southbank center has held my favourite exhibitions in London and each time they are extremely well curated. Definitely a place to visit !
