Hanoi Po Po Guseo-dong Main Branch is a Vietnamese restaurant in a residential alley in Guseo-dong, Busan. It serves chadol pho and mala pho along with pad thai and shrimp rice, and its pho uses thinner noodles than standard pho. Cilantro is given generously on request, and chili can be added to the pho. The space is small with few tables, so there can be a wait at mealtimes.
