I visited this place initially when they re-christened as Nandini. Quality in lunch buffets can go south but at Nandini when I visited the following were what I found to be turn offs :
1. They served rice in a cooker ( could have changed over time)
2. The naans were extremely greasy and charred
3. Almost all the curries I tried were greasy and bland
I hope they have/ will improve and serve better food .
