Visitors can sign up in advance for the free Art Bus Tour, with a lottery deciding who will win a place on the bus.
The tour, led by an experienced guide, travels to three specially chosen events and exhibitions, beginning and ending at Whitechapel Gallery.

In addition to the many culinary hotspots of East London, delicious food is served in the Whitechapel Gallery Café/Bar and Dining Room.
More than 3,000 adults pass through the doors of the Science Museum for its famous Lates events.

For those who want an unusual experience, there’s the opportunity to don a cockroach costume for an unconventional tour of the museum.
Thrill seekers are kept amused with rides on the RAF Typhoon and Red Arrows flight simulators.
