Sinrim Sundaeguk is an old restaurant in the alleys of Sillim-dong, Seoul, serving sundae gukbap and pyeonyuk. The sundae gukbap uses head meat instead of intestines and is boiled with a meat broth base. There are only a few tables, so you may wait during lunch hours. The smell of pork inside the shop is strong, which is difficult if you are sensitive to odors.
