Insadong of Korea is where tradition and modernism meets.
Most recommended to visitors from outside.
Get off at Ankook station exit #6 and you'll find yourself at one end of the Insadong street.
About half way down, there are chattery cheerful chefs in an open kitchen making Ggultarae which is a bundle of honey threads.
Taetmarujib offers best Bibimbabs (traditional dish, rice with assorted mixture of well being stuff).
It's just impossible to explain all the places. Just pop into one and you'll find yourself satisfied.
