CP is the best
Karkardooma one is really nice
I believe the one in Connaught Place is the best. They have a good variety in the Main course, provide quality service and the rooftop arrangement is really nice.
I think it's either Vasant Kunj or the one in Saket. Since they're not much crowded, the service just seems better.
CP on no. 1, or else Unity one mall, Rohini
