Which hotel in Lhasa can provide oxygen and dinner?

Arrived in Lhasa this month 14, stayed for 5 days, and stayed at Xiangyuan Hotel near the city center. Xiangyuan Hotel is invested and built by the national security department of Tibet, which is very safe. Besides, oxygen bottles, rhodiola (a health drink for preventing altitude sickness) and plateau red capsules (for treating acute altitude sickness) are all available, and dinner is also provided. In the peak season, the standard room is 680 a night.
