Well, there is an old Beijing fried belly in Taitung night market. I recommend you to try it. This is a simple little house, which has been open for several years. It is really delicious. Go west from the south gate of Walmart in Taitung. There is a small intersection to enter. On the east side of that small street, there is a shop selling potatoes (French fries are delicious) and an ice cream shop, just opposite them, that is, on the west side of the road. Every time I go shopping, I almost eat their food. O(∩_∩)O~
