Bokdoni Gamasot Sundaeguk is a 24-hour sundae gukbap restaurant between Seolleung Station and Yeoksam Station, behind Shilla Stay Yeoksam and Josun Palace. The sundae gukbap comes with a mild broth and a large portion that fills you up. At weekday lunch peak there is a wait, but tables turn over quickly and seating operates on the first floor and in the basement. Service is not smooth.
