The smallest coffee shop in London

This morning l went to a U3A talk on the artist Carravagio. As l came up, out of Hampstead tube station l saw this BT telephone box which has been transformed into a tiny coffee shop. Now that mobile (cell) phones have taken over the world these boxes are now longer needed and a quick glance on the internet reveals you can buy your own for about £2,000. These bright red boxes are now used in a myriad of ingenious ways from shower cubicles in homes to village lending libraries. I liked this idea and the cheerful owner serves a very good coffee too.
