I heard Malatang is even being served in school lunches haha. Malatang has truly become localized in Korea.

And it's in elementary school lunches, no less
Of course, it must have been fully localized and made milder so that lower elementary students can eat it
I heard stories about people from the Joseon-jok community who used to sell lamb skewers and Guobaorou making huge amounts of money after switching their business to Malatang
