Biryani is a very diverse dish with many influences and flavours; but as others have said and being hyderabadi myself; the only decent commercially available biryani that actually tastes like Hyderabad' is deccan deewan... This is not to say the other places are bad; just that Deccan deewan is the real deal..qatar has some way to go before it can compete with the uae or Saudi Arabia for food though... The biryanis I've eaten there leave even Deccan deewan in the dust...
