Gosuhannip is a restaurant near the DMC food alley in Sangam-dong, Seoul, that serves only one dish: pork pho. The clear pork broth comes with cilantro and garlic vinegar, and the noodles and rice are refilled continuously. The dining room has nine single seats at a U-shaped counter facing the kitchen, divided by transparent partitions. The owner runs the place alone, so food takes time to arrive.
