I've been in there! That's about a five minute walk from the train station, if I'm not mistaken. Lots of shops nearby with naughty books.
I was non smoking at the time, so I ate a special cookie whilst my brother had a good attempt at finishing a Camberwell Carrot.
We (group of four) stopped at a pub that served food on the way back to the hotel, and ate them out of house and home.
