Namdo Sikgaek is a South Korean restaurant in a alley just above the O'sulloc Tea House in Insadong, Seoul. It serves aged kimchi spicy braised galbi and yukjeon naengmyeon, and the yukjeon naengmyeon comes with icy broth, noodles, yukjeon, and pickled radish. The kimchi jjim can be ordered as a single portion, making it an option for a solo meal. The space looks small from the outside, but there are more seats inside than expected.
