Petit Tong is a Swiss-style bakery cafe in the alleys of Tongin-dong in Seochon, Seoul. It serves European fermented breads such as ciabatta and rye bread alongside ham and cheese, smoked salmon, and basil chicken sandwiches, plus vegan cookies. Pretzels, olive ciabatta, campagne, milk bread, and tarts are also sold. The sandwiches use little sauce, so the seasoning is on the mild side.
