Around the American University in Dubai campus there are several business parks around 3 sides, and Sheikh Zayed Road (the main highway of dubai) on the other.
AUD Dorms
The Radisson SAS, Media City, is right across the street from the dorms. They have a nice open air lounge on the 8th floor, and ground level Italian restaurant, Certo.

Dubai Media City sits mainly along the backside of the AUD campus. It is home to CNN, MTV Arabia, Reuters, Associated Press (AP), and hundreds more.

At the base of the dark tower on the left side, there is a Lebanese restaurant called Al Merkaaz. We go there often. It is a nice restaurant with three areas: indoors, patio, and outdoors. We sit indoors when going on special occasions since the seating and environment is fancier. The patio is usually preferred, since there is a TV with crazy movies playing. Here people frequently work on their laptops, while smoking sheesha. It's a good place to study, play cards, hang out, etc. since they love your company. Last night I was there for 5 hours. Other times I have spent 6 and 7 hours there. Since Al Merkaaz is right across the street from the Dubai Media City Park, the outdoor section is an amazing place to listen to the dozens of concerts that take place in the park. Last night we heard t.A.T.u., DJ Aligator, and Dr. Alban live in concert. A month ago at the Dubai Jazz Festival we chilled at Al Merkaaz while listening to David Gray.

HSBC Right outside the dorm gates is the Middle East HSBC Headquarters. I have banked online with HSBC for over a year and a half. I have never seen a branch in the United States, but in Dubai its conveniently the closest building to campus and there are dozens of HSBC ATMs all over the city. This has given me fee-less access to money while other students are paying USD$5.00 per transaction.
