Jung-gu's Ojang-dong may be known for its decades-year-old naengmyeon eateries, but it's got another type of cold noodle dish that deserves to be held in an equally high regard: kong-guksu. Stepping in the humble establishment located in a narrow alley, you'll first notice large pots and an unpretentious open kitchen where ivory-colored dough constantly turns into soft noodles. One rather odd-looking scene you'll encounter here is that, even for a solo diner, a huge amount of kimchi's served. With one bite of the fresh kimchi, though, you'll know why: unfermented yet seasoned with a generous amount of fish sauce, the geotjeori (fresh kimchi) is crispy, pleasantly tangy and oh-so-addictive. At Manna Son Kalguksu, nothing's added to the kong-guksu before it's served, so the kimchi is that much important. The atmosphere, the service and even price (7,000 won) are friendly Manna Son Kalguksu. As the name suggests, also on the menu is kal-guksu priced at 6,000 won.
Some get busy in the summer so they never miss a chance to get this simple meal; others just don’t get why it is even considered ‘food’. Whether it’s an acquired taste or not, the appeal of kong-guksu (cold soybean noodle soup) is in its natural, nutty and oh-so-comforting flavors. Some may consider the combination of just beans, water and salt that go into the soup is way too simple to allow any distinct character. But there are, in fact, many different factors to be found in one bowl to create variations: the type of noodles and garnish, along with how thick or thin the soup is and how savory (or even sweet) it is. We don’t know how you feel about the dish, and we know we can't make you change your mind anyway; it’s for those with delicate taste buds who’ve already got hooked by the simple, milky soup, we’ve prepared a list of great Kong-guksu restaurants in Seoul.
