Tongin Sweet is a dessert shop in Tongin-dong, Jongno-gu, Seoul, near Gyeongbokgung. It sells egg tarts and other tarts, and the classic egg tart has a strong egg flavor and a moist texture; coffee is sold as well. Tarts are served warm right after ordering, so they come straight from the oven. The seating area is small, so takeout is the better option.
