Chengyang consists of a cluster of Dong villages. Dong Village Hotel where I stayed offered both Guilin cuisine and the local Dong cuisine.
Although its menu offered a small selection of food, most dishes were not available. This could be due to the lack of visitors. When I was there, the only other visitors who came were a French couple who arrived at night. Hence, it was understandable that the hotel did not keep a large stock of food. Therefore, guests were obliged to accept the limited choices that were offered.
