Singaporean restaurant in Hongdae: black vinegar guobaorou at Ttasijia
Ttasijia Yeonnam is a Singaporean restaurant in an alley of Yeonnam-dong, near Exit 3 of Hongik University Station in Mapo, Seoul. The order was shrimp broth fried noodles, black vinegar guobaorou (sweet and sour fried pork), chili clams and cold-pressed apple juice, plus a second round of mantou (flower buns) for dipping in the chili clam sauce. Ttasijia Yeonnam is worth a visit if you want something different from the usual Yeonnam-dong menus.
