I know this restaurant has been open for a few years now, and there was some excitement about it when it initially opened.
I was visiting friends in the area and we decided to drop into Nirvana for dinner. Overall this place is a disappointment. Depending on what you order, the food can be bad to average. And it's expensive for what you get. The prices are higher than Copper Chimney for example, and the food is not nearly as good. The only dish that I would order there again is the lamb biryani.
The decor is starting to look old and tired as well. If you are looking for fine Indian dining, this is NOT the place. I will not be going back.
