Seoyeon Guksirak is a noodle shop in Jeonggwan, Busan, serving kimchi noodles and kalguksu. Its eolkeuni kalguksu uses a slightly spicy anchovy broth, and in summer naengkalguksu and kongguksu are available. Payment is prepaid, and gimbap can be ordered as well. Bibim noodles and bibim kalguksu are very spicy, so you must ask for them less spicy when ordering.
