Hey, anyone new in Doha?

Hey,
I am coming to Doha within two weeks.
And therefore I would like to ask you some questions. Since I am gonna work as a waitress/supervisor on the Pearl- do you know this place?

- what should not I forget to bring with me to Doha?

- what kind of clothes to take?

I have been in most countries in Europe, north Africa, Japan but have never been to Middle East (I am kinda interested in this subject so do not give me please the advice like "this is muslim country" etc)

Waiting for your reply!:-)
