Deulnaeeum is a kalguksu shop in a residential alley across from the National Institute of Korean Language in Seoul. It serves deulkkae kalguksu, bajirak kalguksu, and sujebi, with the deulkkae kalguksu and sujebi in deulkkae broth listed as its representative dishes, alongside pat kalguksu, makguksu, and mandu. Every customer receives barley rice and yeolmu before the meal, and each person must order one menu item; ordering fewer items than the number of people incurs an extra charge. Because it sits deep in a residential alley, first-time visitors have trouble finding the location.
