Koreans have distinct pallets. Dong-dweiji is 'Shit pig," and locals will (usually unintentionally) deceive foreigners and refer to it as "black pig." Greg has posted that it's a pig that is raised eating human shit.
That's 100% true.
Boshin-tong is dog soup. Its taste isn't bad. Dog rib bones scared the shit out of me and kept me from ever eating it again. Still, it was not bad.
In general, I hate Korea food, but I won't say there aren't some delicious deishes coming from the hermit kingdom, but Boondaegi certainly isn't one of them - canned or fresh.
