Food review: all day Americana
Focus is very much on all-day dining at the recently spruced up Diner in Camden.

Toddlers takeover the Museum of London Docklands this weekend
Take your little ones to the Museum of London Docklands for a free family festival this weekend with craft and storytelling activities to enjoy.

There will also be a storytelling picnic outside on the quayside, with tales such as The Tiger Who Came To Tea brought to life.
The weekend is a celebration of children’s contributions to museums and is part of the Takeover Day project coordinated by the charity Kids in Museums.
The Toddler takeover at the Museum of London Docklands is on 20-21 May, 10.30am-4pm. Entry is free.
