Busan Uri Ssal Sipwon Ppang is a street dessert shop in Busan that sells cheese bread stamped with the design of a Korean 10-won coin. The basic version holds thick mozzarella, crisp outside and stretching long inside. It is grilled after ordering, and the cheese stretches best while warm; on Sundays there can be a line. Each order is cooked to order, so there is a wait and it does not suit anyone in a hurry.
