Dont worry about the food here, as long as your salary is good and as long as your budget for your food is reasonable, then you can cook whatever you want. and like what i've said as long as your salary in Qatar Riyals is good you can survive here in qatar and you can buy whatever gadget you want. But before you think about that, you should think first about the kind of work you will be having here and the kind of accomodation you will be staying at, and the kind of people you will be working with. Anyway you apply to work here, so you should be prepared on everything once you arrived here. Good Luck and Welcome to Qatar!
