Ganggangsullae Lotte Jamsil is a Korean restaurant in the basement food court of Lotte Department Store in Songpa-gu, Seoul. It serves Korean dishes including galbitang and mul naengmyeon, with the galbitang brought out hot in a single bowl. On weekdays it is open from 10:30 a.m. to 8 p.m. Because it sits in a food court, finding a seat is difficult when it is crowded.
