You'll not be able to provide alcohol so you have to factor this into your plans, which means that you will have to be providing food and service that is way better than anything that the hotels can provide as this is what you will be competing with. I looked into when I first arrived in doha and its not just a matter of finding a place to set up you have a whole barage of certification that you have to obtain before you can even open your doors and the whole proccess takes money, money and more money. Charan is right you still need a sponsor as it is a business. But the main thing that put me off was no liquor as it means if someone has to choose between patroning your establishment and not being able to drink or going to a hotel were they can, if most people are honest the hotel would win.
