Authentic napolitan-style pizza in the beloved Daehak-ro neighborhood and I loved their pizza. Pizzeria O serves an extensive selection of pizza and offers a good wine selection. Three of us ordered pizza buratina, pizza funghi with truffle oil, and spaghetti pomodoro con Buffalo mozarella. We ate it all up and the portkon was perfect. Their tomato sauce is light yet full of taste and the pizza dough is very thin. But despite the description in the menu, I don't think it was proper burata cheese that they used, but just simple mozarella. Also, the spaghetti was not al dente but I think many people in Korea prefer it well cooked. The ambience is nice, they have a nice terrace seating area and the service is friendly. There is no parking space and it's full in the weekend so better to make a reservation ahead. Overall, I really enjoyed my dining experience and highly recommend Pizzeria O!
