Yasik

Yasik is a term referring to South Korea's midnight snack culture.
The dictionary meaning of yasik is 'the food eaten in the middle of the night after dinner.'
Korea's top yasik favourites include: ramyeon, typically eaten with kimchi, chicken and beer, jokbal and bossam, tteokbokki and sundae, gungoguma and hoppang. Kimbap and jokbal is also popular. Past favorites, now less popular, include memilmuk and chapssaltteok.
Fried chicken, first introduced in Korea in the 1980s, and pizza also top the list of night-time favorites. Fried chicken, in particular, has become a wide market, with chicken restaurant chains continually developing new sauces and wooing various Hallyu stars to promote their respective brands. Of course, no late-night chicken order would be complete without a cool pitcher of draft beer.
