Son Kalguksu & Son Mandu serves handmade kalguksu (knife-cut noodles) and mandu inside an apartment complex in Seoul. Lunch includes clear-broth kalguksu and spicy kalguksu, while dinner features dakbokkeumtang with tteoksari available as an add-on. Kalguksu is available for about two hours at weekday lunchtime, and the handmade noodles are chewy. The restaurant is small and located inside the apartment complex, so access is less convenient.
