Well when I was in Dubai it was available everywhere, alcohol played a huge part in the social life out there. It does differ from emirate to emirate. Some of the emirates had a zero tolerance, whilst others required a license to purchase bulk amounts. I'm not actually sure about Abu Dhabi, I can find out in a minute when I speak to a friend from there. I'd be surprised if they didn't allow alcohol sales at a UFC event, simply because the price of alcohol out there is already so high it would just make perfect sense for a very quick profit. We called it a (sin tax) but you'd regularly find yourself paying £5 for a bottle of beer.
I probably was being sarcastic in the above post. I think you should flame me for it.
