[KS] I've eaten it - nice taste, slightly odd texture. Eels used to be a very important part of people's diet in the South and East of England. Like oysters it's had a bit of an up and down ride in terms of prestige.
Eels are now endangered in the UK. There's a big tradition of eating them here in the Netherlands too ('paling'), especially smoked, but the flavour is a bit too strong for me. I suppose I'd eat them if I was absolutely starving and there was nothing else.
I've had smoked eel, thinly sliced on canapés at a provincial art gallery (which I've just realised sounds a bit like the start of an Alan Bennett monologue). Very nice, IMHO. Also, I seem to remember smoked eel paté, but I can't remember when or where. I don't remember disliking it though.
