A lovely, laid-back, quiet rooftop bar and restaurant, with views of the Potala Palace. Pretty much only used by hotel guests, so not raucous, and with no-one hassling you for your table like the rooftop places off Barkhor Square. A perfect place for breakfast, or to let the afternoon and evening slip by.

How very sad that you went here and appear to have totally ignored the appalling treatment the Tibetan people have had - and still receive - from the Chinese occupiers of Tibet. Please research Tibet to find out the true situation.
Is this your business?
