Last year for the very first time I eat an octopus, how they cook it is quite simple, they boiled it then they fried it, eat it with rice, veggies, and a fresh chili (crushed, like lots of them), best thing ever, not really a restaurant quality since I eat it in a fisherman's house (he hunted those octopus by himself) in a relatively isolated village by the coast but because all of them are fresh it's very tasty.
