Heo nướng lu Ông Phú Đạt is a sandwich shop in Da Nang that sells bánh mì filled with pork belly roasted in a clay pot. The bánh mì comes with chili sauce and vegetables added to the pork belly, which has a crisp outside and moist inside. Pork is roasted continuously in clay pots in front of the shop, and when an order comes in it is chopped with a knife to make the bánh mì. The shop faces west, so eating without takeout is hot.
