Bak Sin-u Jemyeonso is an udon restaurant in Gyeongju that makes hand-pulled noodles. Its menu centers on burdock tempura udon and soy sauce mixed udon, and each noodle is pulled long and chewy. Reservations are required before visiting, and there is a waiting number machine at the entrance and a waiting area inside. Orders are placed at a kiosk before sitting, and cooking starts immediately after, so it takes a little time; the broth udon is lightly salted, so the house soy sauce and wasabi are adjusted separately.
