I have been there a number of times and I just love their South Indian food. I specially order Onion Rawa Masala Dosa and its really very tasty. Their papad is also pretty good and crunchy. The ambience is good, A/C works perfectly and lights are bot over bright. The staff is quite courteous and the delivery time is very fast. The chutney that they offer with Dosa is quite yummy.
I think they serve really good South Indian cuisine in Delhi and you must try the same.
