Constantine;
GCC refers to 'Gulf Cooperation Council' and basically refers to all the countries of the northern Arabian Peninsula. It would be wrong to say 'Arabic experience'
and there's more around here than just the UAE.
Food here isn't too expensive but getting sloshed on quality wine while you dine would hurt your wallet.
A _good_ meal for two with a glass or two of wine would cost about 300AED (about 80USD) - this would be at a five-star hotel reasonable restaurant with a view / ambience.
A nice meal for two with a couple of beers would cost up to 200AED (think nice Italian restaurant)
If you like Indian food then some of the best biryani I've eaten has been in Bur Dubai (no alcohol licence though) and you could leave there smiling for 15AED ...
You won't struggle to spend your money here (if you want to spend your money) as there's a lot to tempt you. Hehe ... (secondhand) Ferrari Testarossa for 3,000 AED/month installments anyone??

PS. The *only* thing to beware of in Dubai is rent. You'll have to pay one year in advance - so bring cash with you. Most employers at the 20k level won't provide accommodation. If you're going to be working in Dubai Media City there are a lot of late 20's early 30's expats flat-sharing in The Greens - which is about 3km (and 20 minutes!!) away.
