Oliphephe Gwanghwamun is a large Italian restaurant in Gwanghwamun beside Cheonggyecheon. Its main offering is wood-fired pizza, and the signature dish is clam bianca topped with plenty of clams. Floor-to-ceiling windows look out onto Cheonggyecheon, and the dining room is crowded at both lunch and dinner, so reservations are recommended. The food is plain rather than bold or distinctive.
