Abai Tojong Sundaeguk is a restaurant in Seoul that serves sundaeguk and suyuk. The sundaeguk mixes sundae and offal, and a sundae-tang with only sundae is also available, served with kimchi and kkakdugi. The restaurant draws enough customers to form a line at 2 p.m. on Sundays, and it previously operated under the name Mubongri Sundaeguk. The taste has changed from before.
