Well, it's not quite in the heart of Abu Dhabi but there is this place called Masdar City, which is actually just around the corner from our temporary apartment. Our friend suggested we all go to a Japanese restaurant there. Right now there are just businesses there and also a university, but eventually it will be a residential area as well.
This city thrives on being it's own sustainable community - leaving as little as possible on the environmental footprint. So that means, using solar power and lots of recycling from what we could see. And... these amazing looking electric cars!
