I have, on earlier occasions, been to Sigree. I have to say that the restaurant has slipped a bit. It could be a good place for a small group (~4), but anything that is a large group is a number of covers that they don't have competent staff to handle.
The weekday lunch is a bit of a jostling crowd at the buffet table and, the spread is not so spectacular. Just so. A group of us (18, to be exact) were at this place on the 27th. And, it wasn't a really enjoyable experience. There are certain basic bits that a restaurant needs to have down as a routine. An example, glasses of water at the table. It took 15 minutes and asking twice before glasses were filled up. Then, it is the duty of the table staff to ensure that there is a complete set of cutlery - sadly, that was lacking. It is also expected that the staff would take care to serve the soups, appetizers and food as they are ready. Instead, the food was left at the counter and, after inordinate delay was served (for those who chose to order off the menu).
The naan(s) served were cold. The Methi Malai Murg was probably the one dish which would pass muster. The Kakori Kebabs were served singed and, it would have been a terribly burnt after-taste if one was to eat them.
However, what I found most annoying and, quirky was the insistence of the on-floor manager to know how the food was, right between meals. Even after pointing out that a feedback form or, an after-meal discussion would be appreciated, it was very hard to convince him to let us be. I appreciate the need to receive feedback, but interrupting a meal that is already going south is something that is well out of the ordinary.
I wouldn't really recommend Sigree for large groups. Especially on weekdays.
