I used to go Arsalan, park street Kolkata several time in a month with my friends and family. This is one of my favourite restaurant. If their is any question about Mughlai preparation then I suggest for this restaurant because I think this is the best restaurant in Kolkata for Mughlai preparation in this price range. I went to Arsalan, park circus 2 to 3 times. But is not as good as Arsanal, park street. They are specialist in Biryani and chicken tandoori.
So, I like to suggest you for this restaurant you will love it.
