not a high point but museum of islamic art will be a good point of view after its opening.

You can see all of the corniche, around city centre(mall I mean) it seems like Manhattan with all skyscrapers...
The other issue that makes it different I think is; it is in the sea...

as rayyz, I also find al shaheen of Sheraton amazing with its scenery... I want to see four seasons's. Any one saw ?
