Udon Myeongga Giriyama Bonjin is an udon restaurant in a basement alley off Gangnam Station, serving thin noodles and sushi. Its zaru udon is dipped in a tsuyu broth made with grated yam, and a miso donkatsu with miso sauce and a sushi set are also available. Waiting guests leave only their party size, then sit down to choose and order from the menu. Lunch draws a wait of around 30 minutes, and the crowd thins after 1 p.m. on weekdays.
