Also coming to mind is the scene in the Florida rest area from "There's Something About Mary."

OK, enough, point made, I'll stop!

Flattened by the Victoria to Stansted Terravision shuttle no less

There is also "Public Life" the underground toilet bar outside Christchurch Spitalfields

Someone really needs to start a thread compiling the best places to find a loo in central London. IME, London shops are very loo-unfriendly and those that are freely open to the public - Burger King comes to mind - are often filthy. My preferred location is Waterstone's, always clean, no hassle.

Yup, I tend to head for book shops, too. Problem is, I tend to get sidetracked looking at books, and lose an hour in there... Coffee places are normally OK - there are even some parts of London where the local authority pays them to open their toilets to the general public.

The public ones at Covent Garden are surprisingly good, as are the only Tube ones I know at Farringdon (although I think they're shut during Crossrail works).

Reading this thread and associated googling leads to a sick feeling..
my lunch is barely staying down

;)

I also like the Trafalgar Square ones. Kind of like the death star toilets: everything is made of shiny chrome and mirror glass. Continuously cleaned.

Don't worry, the OP will be back soon protesting that he did not know what was going on at car parks in the country and someone should have warned him, so we can change the subject then. :D

Piccadilly Circus, Green Park and Bank Tube stations all have public toilets.

I do think that it would be worthwhile opening a premium and paid for chain of ladies lavatories and dressing rooms.

Charge GBP 5 for admittance during the day and maybe GBP 10 and have plenty of clean lavatories and a separate powder room with plenty of seats and mirrors.

Also have fresh flowers, linen towels and a selection of amenities. And of course it would be well lit inside and around the entrance.

I am sure that many ladies would pay for such a facility.

Not sure if you're being serious or not, but I've often thought that there would be a good business opportunity for someone to open a clean, pay for use lavatory only facility in very busy cities.

Absolutely serious! :)

Great, let's go into business together! :p

Of course you'd need a loyalty scheme.
"Priority P!$$" perhaps?

Frequent users get upgraded access to the throne room?
