We went to Adaa for dinner during our trip to hyderabad. Usually i think they take dinner reservations at 7.30 and 9.30. The tour (included in the dinner reservation) starts at 7.00pm and 9.00pm. The first thing that comes to the mind when you enter this place is "Opulence". The experience is just awesome, the palace seems to be kept the way it was when the Nizam was living here. The food at the adaa is very rich and tasty, though understandably very expensive. The biggest problem we had with this place was the rude staff. They refused to accommodate any requests and the waiter seemed quite pissed at us towards the end of the meal. Not what I expected from a Taj Hotel. But the overall experience of dining in a palace where the richest man in the world once lived is unrivaled and so I still rate this place at 5.
