Great experience, however very expensive and you can eat just as well for a quarter of the price.
The meat and the dahl was the best I had in India however.
We went the banquet and it was far too much food and was part of the reason the cost was so much.
The service was great, the waiters had a great sense of humor and were happy to chat.
It is authentic, but in a touristy type of way, hence why the place is full of tourists and business people.
