Hwamok Sundae Guk specializes in sundae and sits on the first floor of Gyeongdo Sangga, a five-minute walk from Exit 2 of Yeouido Saetgang Station. Its sundae guk contains both gopchang and chalsundae, while the naejangtang is made with gopchang only. Waits are common, and solo diners may be seated at a shared table with other solo diners. A drawback is the distinctive smell of pork intestines.
