This place is a 'heaven' for many people in Kozhikode and especially those who love Malabar biryani. This is one restaurant which I forgot to review and I had multiple people asking me "How could you forget the iconic Rahmath ?". This restaurant by far is considered the most reasonably priced. I have tried their chicken, beef and mutton biryani and I honestly didn't find their mutton biryani that great but beef and chicken was really awesome. It is a very simple place with simple interiors including a family space upstairs. It is located at Mananchira, a crowded area but I think it is easy to locate as there is surely no one in Calicut who isn't aware of this place. Though I have been there twice now, I prefer to visit them again for their Kada Biryani ( Quail biryani, read about it online and hope they still serve it) and Mutton Stew. The service is absolutely quick and staff is very friendly. Overall this place is must try when you are in Calicut.
