Never eaten in the hotel, but I regularly pick up food from here. Love the taste and really like the fact that it's consistent.
Last evening, when I ordered for 2 biryanis and a chilli chicken, the delivery was made within about 30-40 minutes and the delivery guy was courteous. The thing that put me off a little was that he told me that they've delivered Chinese-style chilli chicken! I didn't expect a hotel named Hyderabadi Biryani to have any Chinese-style food.
That being said, the Chiinese style chilli chicken was pretty good. :) Enjoy maadi!
