Hi,
I've just relocated to Doha 3 weeks ago,may be was a wrong timing for us to landed here,everywhere seems like either closed for summer or on waiting list,but after a while we managed to make some new friends.
You can get a Marhaba(qatar's information guide)from book stores or hypermarkets,there are plenty info. such as schools,malls,clubs,activities etc.
By the way,here you can find brownies in every cafe outlets.
