A medium sized, rather plain lounge, designed just for Frequent Flyers in economy, the Doha Qatar Airways Silver Lounge is a bit hidden away, but a useful pit stop in the hub that is Doha Airport.
The Doha Silver Lounge has comfy seats, a free bar and buffet catering. There is hot food 24 hours a day, salads, and sandwiches.
However, if you are in Business Class on Qatar, there are much better lounges.
