Where can I take Korean culture classes like cooking, calligraphy, traditional arts, and other cultural activities?

There are loads of options, and many are free or cheap for foreigners. Your first stop should be a Global Center or 다문화가족지원센터, a multicultural family support center. The Seoul Global Center near City Hall runs cooking, K-pop dance, calligraphy, and Korean language classes, and there are branch centers in areas like Yeongdeungpo and Itaewon.

For cooking specifically, places like O'ngo Food Communications and royal cuisine institutes run hands-on classes in English. If you like traditional arts, the National Gugak Center teaches Korean instruments and dance, and the National Folk Museum and Korea Foundation offer hanji craft and tea ceremony sessions. Department store culture centers (문화센터) inside Lotte and Hyundai have very affordable weekend courses on everything from pottery to flower arranging. Temples around the country run Templestay programs with meditation, lotus lantern making, and monastic meals, all available in English. It is also worth checking your district office (구청) website, since they regularly post free seasonal programs for residents. Most of these just need online sign-up and your ARC to join.
