The Gents in the Himalaya building was quite interesting - I don't think I've ever seen a toilet with a glass wall before! I had imagined it was more like a hide, where you could see the aviary through a long slit above the urinals. The leafcutting ants toddling round the mirror were a surprise too. I couldn't help wondering if the Ladies has a better view?
I haven't been since the 'New England Wetland Toilets Window' was opened, but the more I hear the less I am enthused. Why are they forcing people to hang around the toilets to see animals?
