Kkuwak Kalguksu is a small noodle shop in the alleys of Euljiro that serves kalguksu, mandu, and kimchi bokkeum bap. The kalguksu comes with mung bean sprouts and minced meat on top, clear meat broth like pho, and chewy noodles, while the kimchi bokkeum bap keeps its charred wok flavor and scorched-rice texture. Customers write their name and party size on a whiteboard and wait, and even though the shop opens at 11:30 a.m., a line of around 30 minutes forms at lunch. The interior is narrow, so it stays crowded throughout the meal.
