Hello Viet is a Vietnamese restaurant in a residential alley in Seoul that serves pho and bun cha. The pho broth is rich with meat, closer to seolleongtang or gomtang than to a sour profile, and the bun cha comes with meat that has a charred flavor. The menu is short, so choosing individual dishes is simple, and the pho comes with a generous amount of noodles and meat. There is nowhere to park, so going by car is difficult.
