Carnegie Mellon has set up it's own Wiki for Qatar including restaurant suggestions. The URL is: http://www.qatar.cmu.edu/alhannah

The Restaurant guide is at:

The advice seems pretty good. Just discovered the site today. Well done CMU. The only thing missing (IMHO) is GPS coordinates so that a location can be found using maps.google.com. I'm tired of people telling me that something is near TV roundabout.
