I took American - real slop. The only more or less normal coffee in this area is at the Fix cafe (it's opposite the entrance to the hall, for some reason it's not on the map yet)
It's expensive and not that delicious. Buying coffee in countries where it is consumed in huge quantities and there is an established culture of drinking this drink, you expect more.
You can sometimes go in and drink good coffee with them when there is nothing to do. The only one in Emirates is bad, because there are a lot of immigrants.
