Mongolian hot pot is not a fondue..

but is known as fondue chinoise in French, and I think Chinese Fondue in UK English. (Our family tends to use the French phrase because we eat it in Switzerland - I have never seen the thinly sliced meat in UK). Proper chocolate Fondues have a gentler heat source like a night light rather than a burner. Fondue Bourgignon uses a metal pot to hold the oil but on the same wide stable base we use for heating cheese. And we usually get pleasently merry during and after the fondue, rather than before.
Anyway, I like fondues because it is difficult for my wife to see how much I am eating.
