After our cherry blossom viewing, we walked back towards 여의도역 Yeouido Station 汝矣島站, and the IFC Mall was nearby, with plenty of food options. Since we wanted to have Korean food, we opted for 사리원 Sariwon Bulgogi, which had pretty good online reviews.
The menu was available in English, Chinese and Korean, and we took a lunch special 육수 불고기세트 (Yuksu Bulgogi Seteu) Hand Marinated Prime Beef with Broth Set 肉湯烤肉套餐 (₩18,500 per person).
We found the 냉면 (Naengmyeon) Cold Buckwheat Noodles 冷麵 to be the highlight of the meal. Delightfully chilled, we enjoyed the texture of the noodles very much. The beef was so-so. Not exactly a satisfying or cheap meal, but well, it was located in a mall.
