Talal Abu Ghazaleh Knowledge Society (مجتمع طلال أبو غزالة للمعرفة) was a great place to study, network and make friends.
It included study desks, computer workstations (with Internet) and private seminar rooms. There were also classes, e.g. English, etc, and – for a limited period – a half-hearted colloquial Arabic conversation club.
It used to be free, but the membership benefits were well worth the fee that was later introduced. I did not think twice about signing up.
After they moved location, I never visited again. I was still in Amman, but some place I never frequented. However, the former location was taker over by the Ali Baba library, which was mostly a good experience.
Unfortunately, although TAG has succeeded in many areas, they were unable to provide a useful framework for learning Arabic.
