Bel Amine
I think what most people would be shocked to find out is that Dubai is quite the sin city, very popular sex tourism destination. Also, I've had someone I knew go to jail but it wasn't a serious offense and it didn't seem that bad. It's actually a pretty chill place, very low crime rate. Just don't do anything you wouldn't do anywhere else and you should be fine.
Yep, there are some very seedy bars with what the local Time Out referred to as "overtly friendly female clientele" if you are looking for that sort of thing. Pretty much all human life is here.
The older part of the city (like more that 20 years

) has lots or really good ethnic restaurants catering to the diverse international population. Unfortunately in the newer areas chain restaurants are the order of the day.
