Bubu Son Kalguksu is a small noodle shop in Busan that serves kalguksu and sujebi. The bibim kalguksu balances noodles and seasoning well, and the hand-made noodles have a chewy texture. The shop also sells mandu alongside the kalguksu and sujebi, and the broth is cool and clean. The kimchi is sweet, which sets it apart from mild geotjeori.
