Another reason to love winter in Korea is its seasonal street food, namely roasted sweet potatoes and chestnuts. These flavorful snacks are not only cheap and delicious, but also healthy. Unlike other street foods, these don't need salt, sugar, or other seasonings to taste yummy.
These snacks are especially aplenty in Seoul during the winter months. You can smell pleasant flavours at every other street corner, or near subway stations. It's most advisable to try rare treats in older districts like Insadong, Jonggak, and Jongno. For sweet potatoes also visit the festival held nearby Sileuksa in early January.
