Cost of living is not that cheap here.
For example, if you drink at all you'll pay QR6 for one beer at QDC (the only place you can buy alcohol from). If you're having the same beer at a hotel, I think you'll pay about QR25. I stand to be corrected on the price of beer as I've only had wine. For a glass of red I paid QR50. Yes, for one glass!
I went to Macaroni Grill (an American restaurant) and paid QR130 for a main course and a desert.
The Indian joint near my flat charges QR14 for one meal plus QR2 for delivery.
