10. Nakji bokkeum
Nakji bokkeum -- stir-fried octopus -- is one of South Korea's spiciest dishes.
It is believed to have been invented in a tavern in the Mugyo-dong district of Seoul in 1965 by a grandmother named Park Mu-sun.
Nakji bokkeum quickly caught on. Word spread, and a national favorite was born. Now part of the modern-day Myeongdong district, Mugyo-dong was the most fashionable area in Seoul at the time.
Still today, if you poke around enough, you can still find some of those old nakji bokkeum joints in Myeongdong.
