The toilets in St David's Dewi Sant are second to no other public loos in Cardiff. They don't cost anything to use and are checked regularly so you can be almost certain that you are not going to find some horrific mess that some unruly character may have left behind. As Andrew has said, they are fitted with the Dyson Airblade hand dryers. I'm not quite as enthusiastic as Andrew about them but we have the same ones installed where I work so I guess this is the norm for me now. Basically, Mr. Dyson has invented a dryer that churns out a specified "blade" of air so when you put your hands in, all you need to do is draw them back out slowly and the blade of air will do its thing. I always giggle when I use these as the air gets caught in one of my rings and whistles. Combine that with trying to make parts of your hand skin flap and you could have loads of fun in the toilets in St. David's Dewi Sant. read more
