I haven't been here, but did a lot of research when I was supposed to do a project for the government there. I think it is Doha, in Qatar.

p.s. I got the contract, managed to get a license to purchase and drink liquor, got my visa and then just as I was finalizing everything and had my housing lined up, the agency called up and said that conditions had changed and that they were going to reduce my negotiated daily rates. They seemed very surprised when I respectfully declined to accept less pay (it seems that this rate reduction is almost a standard practice) and two weeks later I was in Denmark doing a project when they contacted me again regarding "renegotiation". You can imagine how well that went, particularly as Copenhagen is a great place to work and live!
