Tanghwa Kungfu Yeonnam is a Chinese restaurant in Yeonnam, Seoul, serving malatang and guobaorou. The malatang has a distinct huajiao aroma, and many orders add guobaorou alongside it. You fill a bowl with the ingredients you want, pay by weight, and choose a spice level. Level 2 is numbing enough to paralyze the mouth, so beginners should start at level 1.
