Itaeri Gwangsu is a small restaurant in the alleyways of a university district in Busan that serves pasta, calzone, and pilaf. The sweet potato calzone tastes like sweet potato cheese pizza, and the red aglio has a flavor closer to stir-fried udon. A set order provides enough food for two people to eat until full, and the salad dressing has a distinct flavor. The shop is small, so seating is cramped.
