Donggyeong Gyudong Geondaejeom is a Japanese restaurant in Geondae, Seoul, serving gyudong and donburi. It offers mentaiko mayo yaki gyudong, katsudon, and soft-boiled eggs, with sweet soup. Parking is available at a nearby public parking lot, within 10 minutes each way at a slow walking pace. The udon is large and the gyudong small in the udon and gyudong set, while the gyudong has unsatisfying beef texture and flavor.
