I like eel quite a bit, although the first time I tried it was not pleasant and put me off of it for a long time. Both times I had it, it was in a sushi roll. I suppose the first time it just wasn't all that fresh or something, because it just tasted bad. I thought for sure I would love it, since I'm pretty much obsessed with eating anything that swims, but I was wrong.
Thankfully I tried it again, very recently actually, at a much better establishment. It has a very distinct flavor, which may not be for everyone. And quite frankly, in my opinion, it's a little ugly. But it is tasty. It has a melt-in-your-mouth quality kind of like a very fatty piece of sashimi might.
So, I do enjoy it. But in the realm of sea critters, it's far from my favorite.
