Lanzhou.

1. Lhasa is a fourth-tier city, a prefecture-level city under the jurisdiction of the Tibet Autonomous Region, and Lanzhou is a second-tier city and the capital of Gansu Province. Lanzhou’s economy is more developed than Lhasa, and the food delivery industry is more profitable, so Lanzhou is better for food delivery.

2. Lanzhou has convenient transportation. Lhasa is a city with high altitude, many mountain roads and inconvenient transportation, so Lanzhou is good for food delivery.
