Old Sundae Gamjatang serves sundae guk, dwaeji gukbap, and bone haejang-guk, and sits in the Baekje Pharmacy alley running from Jongno 5-ga toward Dongdaemun. The sundae guk has a clear, rich broth without pork smell, and the dwaeji gukbap is mild. Long-time regulars eat here, and sundae and offal dishes can be ordered alongside. The restaurant has been run by three generations, and portions are small for the price.
