1) Dubai at night, probably the most spectacular skyline I have seen. Plus this is the only time when you can actually wonder on the streets without burning alive

2) Women and children only subway carriages (even though they may be considered as a representation of gender segregation)

3) If you have got the money and want to really indulge yourself - Dubai has it all

4) Ban on chewing gum in public spaces. It used to be illegal (or may still be) to chew gum in Singapore too (you actually needed a prescription to get it)

5) Old Deira - although, this is not the place to be a rebel so make sure you cover yourself
