Anyone interested in this topic and in the UK .... or are lucky enough to be in an airport lounge with a copy ...... might like to look at Alexie Sayle's wonderful article in The Times (UK) on his passion for All You Can Eat Buffets. It's one of the funniest articles I've read. Also online on their subscription site - "How I fell in love with all you can eat bufffets ..."
It's worth the £1 trial subscription alone .....
