South atlantic squid tentacles and head are very tasty, however the rest of the body (which people generally value the most) is not very enjoyable for me. Also it's really hard to find fresh squid where I live, almost all is frozen. Octopus I've only had once, from Spain (frozen), and it was really chewy. Never had any of them live. I hear you gotta make sure to chew them really well because the tentacles can attach to your throat and smother you.
