anybody needing the loo whilst out and about should visit the ICA on the Mall. There is a fee to go to the exhibits or the bar but the clean, well furnished toilets are right by the entrance and free! The exhibitions are sometimes a little bare, incuding the high profile BEcks Futures but they do have some interesting talks and the odd juicy film preview. If you are not a member then you can buy a day membership which is basically a ticket to whiever event you go and see plus access to the bar…and more toilets.
