For self-driving passengers, I recommend Yilan Restaurant next to Xiamen Bridge, Datong Hui Autonomous County, north of Xining. Friends of Qinghai Gansu self-driving tours departed from Lanzhou in the morning and drove by here. It happened to be noon. There were many tour groups of buses that also carried passengers here for Chinese food. The taste of Xinjiang's large chicken is very authentic and the portion is sufficient; the farmer's roast potatoes are fragrant and crisp, but these two dishes wait a little longer. The noodles are the fastest, and the rice in Qinghai Gansu area is more expensive, and it is more cost-effective to eat noodles. You can taste the yak yogurt made by the restaurant yourself, 5 yuan/bowl, not sweet enough to add sugar yourself. The homemade yogurt at the personal stall on the road is 3 yuan/bowl, which is not delicious and overfermented. In addition, the free tea at Yilan Restaurant is red date longan tea, which tastes strong and delicious, but customers have to pour it themselves. When we finished our meal, everyone brought another cup of road drink with their own cup, give him a compliment!
