80-Year Traditional Original Sundae Guk is a Korean restaurant serving bean sprout sundae guk at the entrance of the relocation complex near Gangseo Agricultural and Marine Products Market in Seoul. The signature sundae guk contains makchang (beef abomasum) sundae and head meat, and the bean sprouts give the broth a spicy, refreshing taste, with the seasoning sauce served on the side. The restaurant began in 2004 near Mayfield Hotel and later moved to its current location, and there can be a wait at lunchtime. Parking is difficult near Gangseo Agricultural and Marine Products Market because of vehicles from nearby shops.
