Jinsundae Gomtang in Seoul serves gopchang sundae guk, sundae, and suyuk. The gopchang sundae guk is rich and nutty without any off-putting smell, and it works with minced garlic or kkakdugi broth added in. The restaurant is used for neighborhood dinners and as a meeting spot for residents' drinking plans, and takeout is available for family portions after eating in. The gopchang sundae guk can taste heavy to those not used to sundae guk.
