Sorry to burst your bubbles peeps..

Yes, indeed there are two Al Mana Towers..

1. Commonly known as Toyota Tower, Abdulla Abdul Ghani on Najma intersection. You can see a huge building as you take right on C ring road towards the Airport.

2. The second one is in Bin Mahmood, not in Al Sadd. And McD's and Applebee's etc are in Fareej Nasr, not Al Sadd.

The New Almana Tower has nothing to do with Al Sadd, as you all are saying.

Just my two cents. :)
