Accessible tube in London

On Sunday, Naomi and I went to London to see  " A major exhibition of Chinese contemporary art, architecture and sound"  China Power Station: Part I by the Serpentine Gallery at the Battersea Power Station. Since Yin worked there, she got us free entry. She picked us up at Euston with her mum and we had dim sum in Chinatown. Anushka was to join us but she was a bit late and we did not want to hold up the table so poor Anu missed the dim sum. (not sure she would have like it since we had chickens feet and pigs intestines and preserved eggs congee.

I knew i would regret not taking my camera. The exhibits as I expected were not to be photographed for copyright reasons but the power station where they were held would have been great in shots. One of the exhibits was a wall of apples in wire - some of them had begun rotting so there was a permeating smell of fermentation like cider gone off.

Since then someone at SCOPE had informed me that there is a map of accessible tube online. I am looking forward to trying it out. I have never been to the London Underground before.
