Shopping is all very much Tourist focused here, if you want to shop you are going to have to go out of the Airport. The Emirates First ClassLounge is nice.
Passenger have to walk 20_25 minutes to reach their gates, services are to small the dobt think that maybe you have a trolly or big backpack, after gates there is nothing no water, eat and toilet
Terminal 3 is too narrow at the duty free to navigate or to get to a gate quickly....... I think they were to interested in getting to to spend money than make it practical...
