If you happen to be in Hyderabad and wish to taste some authentic local cuisine and soak in a great lounge like atmosphere, then do visit the Nirvana Restaurant. This tastefully done up lounge-restaurant is located on the 4th floor of Lumbini Mall on Road No.2, Banjara Hills.
This place has an amazing bar and an excellent kitchen. My friends swear by the Nizami Murgh Biryani here. Me being a vegetarian, I can only vouch for their vegetarian fare.
The service is excellent and the dimly-lit paths surrounded by waterways, fountains and rose-petals is certainly very soothing. These guys have an exhaustive menu dealing in Indian, Hyderabadi, Italian and Mediterranean dishes. The food is fairly priced. For such an ambience and taste, the cost is very much within reach.
I like this place so much that I tend to plonk myself for at least a couple of hours during my every single visit to Hyderabad.
