Duabi is full to the brim with international joints like Pizza Hut, Subway, Burger King, KFC and what not. It has a wide variety of fast food joints ranging from traditional Thai cuisine to spicy Indian cuisine!
Most of these joints are fairly priced. Take Burger King for example. An average burger+coke+fries combo would cost you around 6$-7$ at the most. Compared to the other restaurants in town, these joints are a good way to save on money and catch up on lost time.
There are also many Mexican food joints, some situated inside local markets, thus making them the ideal stop to eat while shopping. Do not mistake local markets for Malls. Malls form a separate segment altogether. I'll come to that later.
