I managed a quick visit to this lounge upon my departure from Pyongyang, North Korea. The lounge itself was not really special. It had a assortment of fruit, snacks and drinks. The only way to get in to this lounge is basically flying Business Class with Air Koryo or Air China on those few occasions they fly to Pyongyang during summertime.
The staff was friendly and spoke good English and payed very much attention to the customers needs. However I would have liked a hot food option for breakfast, but I can understand why they don't have it since my flight was the only flight out from the airport that day.
Overall a good lounge, have seen much worse. Enjoy the pictures down below.
