- Minar, Connaught Place
- Moti Mahal, Daryaganj
- Kake Da Hotel, Connaught Place
- Kwality, Connaught Place
Apart from these I had personally tried
- Invitation, Ashok Vihar
- Galena, Gole Market
After I published my last post, I got 2 more recommendations
- Gulati, Pandara Road
- Rajinder Da Dhaba, Safdarjung
Additionally, I also tried a new place
- Above and Beyond, Kirti Nagar
And the top two places to savour sumptous Butter Chicken are
1. Invitation, Ashok Vihar
2. Above and Beyond, Kirti Nagar
Galena would have been third but has unfortunately shut down.
All others except Gulati (which is average) are a waste. The dish they serve in the name of Butter Chicken is anything but Butter Chicken.
One more place I have heard about is Havmore, Pandara Road (next to Gulati's). I sincerely hope it takes the number 3 spot. Would update once I try!
[UPDATE Apr 16, 2017] - Late in updating but I tried Havmore, Pandara Road and Moti Mahal (Mahipalpur). While Havemore did not make the cut, I was pleasantly surprised with Moti Mahal (Mahipalpur). Was overwhelmed to an extent that I think I'll try all top 3 again to reshuffle ratings - Yes, was that good!
