I remember the time I paid 5 GBP for Biopot yoghurt at MegaMart. Or 20GBP for a hamburger (it was a good one at Paloma's but I never did that again.) I think it's a minimum of 2,000 QR to rent a car here. And you need a car since there is no real public transportation. Taxis are about the same price as in the UK.
