Bangkok Guksu is a Thai restaurant in Busan's Haeridan-gil that serves beef pho and Thai-style rice bowls. The pho comes with a rich meat broth, and the pad kaprao moo sab is also on the menu; ordering one dish per person allows unlimited refills of rice and noodles. Cilantro is served on the side so diners can add it to taste, and the beef is thick and tender. The sign is small, which makes the restaurant hard to find.
