I was part of the construction and management of two chemical plants in South Korea, was over there weeks at a time for a few years. Ate all the usual stuff but the most memorable was some octopus. I already had eaten my body weight in octopus sashimi so I didn't think twice when they brought over a small plate of cut up legs, my Korean handlers motioned for me to take some so I should have been tipped off right there it was not what I expected. Sure enough, I put a few pieces in my mouth and the suckers immediately started attaching themselves to my gums and teeth and tongue making it not only a surprise but that much harder to chew.
I forgot about the octopus. Yeah you have to chew it very thoroughly. The first time i ate it i actually had a tentacle stuck in my throat for a few second. Beer and Soju washed it down pretty quick. It is kind of cool to be able to walk through the stalls and pick the octopus that you want to eat. They will chop it up for you and then hand it to you ready to eat.
No wonder it has to be hot spiced to cover that taste. Absolutely terrible.
There are actually a few hundred different types of Kimchi. I havent heard of squid in kimchi but i do know they have raw oysters in kimchi. I guess i am used to it but i really like most types of kimchi. Granted my breath smells like garlic for a few days but it is a small price to pay for some fermented goodness.
