Bwalla Cafe is a small cafe in Marine City, Haeundae, Busan, selling sea-salt ice cream and salt latte. Its signature items are ice cream made by rapidly cooling milk ingredients with liquid nitrogen right after ordering, and salt coffee. Order and pay at a kiosk, take a number ticket, and pick up the food when the pager buzzes. Indoor seating is limited and the chairs are hard, making the seats uncomfortable.
