My experience was in Spain, where they’re pulled right out of the Mediterranean. Most were very tasty, but there were a couple of bumps...
the last time I had them they were tiny little almost-whole ones, at an Asian buffet restaurant. (What are those called?)
Unless in the future I can try them at a really fancy restaurant, I think I’ll pass :-)
My wife dined on them in Spain. She liked it until she noticed the little suckers on the small tentacles. She asked what they were and I told her. I ate the rest of her soup. It was delicious.
