Genroku Udon Gyeongseongdae Bukyeongdae Branch is an udon restaurant in Busan that serves beef nikku udon and chicken jidori udon. The noodles are made from Gangwon-do wheat and buckwheat, aged for a chewy texture, and the nikku udon contains beef while the jidori udon contains chicken and grilled green onion. Orders are placed on a tablet at each table, extra noodles and double or triple portions are free, and the kitchen closes at 8 p.m. The space inside is not large, so a wait forms during meal times.
