Dear Humphrey & Sam I visited the Duke Of Argyll pub yesterday whilst London. Whilst waiting nearly 15 minutes to use the one female toilet in the venue I pondered why there were 2 basins in the said venue. My general chit chat with the other women in the queue could only suggest they were there so we could wash one hand in each basin. I'm hoping this venue will be updated soon and offer more facilities. I know the area was busy yesterday as it was the LGBT pride march but I'm sure it is not the only busy time for this pub.
