Burger Groo 72 Yongsan is a handmade burger shop on the basement first floor of the Amorepacific headquarters building near Sinyongsan Station in Seoul. The buns stand out, and the patty doneness can be adjusted. Orders are taken at the front, where customers decide on the menu before waiting, and a line forms during lunch hours. Onion rings and french fries are less satisfying than the burgers.
