Seonjin Sikpum Bonggung Sundaeguk Main Branch is a sundae-guk restaurant run directly by Seonjin Sikpum at the entrance of the Ansan Tecom complex in Ansan. The base sundae-guk uses sagol broth, with variations including two-whole-san-nakji sundae-guk, dried radish greens sundae-guk, and bulkkot sundae-guk. At lunch, customers take a waiting number and wait, with rice and sungnyung available for unlimited refills. During peak hours the restaurant's own parking lot is insufficient, so parking must be done outside.
