Two teahouses in Someyeon (downtown Busan) have closed. Both are relatively new compared with the others. However both had their own unique character and it is sad to see them go.
In Japanese and English it is called Matcha, in Korean its Malcha 말차. In Busan today, there are two places that serve green tea that way, the best of which is in Someyeon at a place called DaSoul.
Back in the 1200s green tea was drunken in powdered form, in bowls, wisked to a froth with a bamboo wisk. This occurred in China, Korea and Japan. At the end of the 1200s the mongols invaded, somehow wiping out this tea culture. As the mongols weren't able to successfully invade Japan, it survived there, later becoming the Japanese tea ceremony.
