Royal indian hotel is my favourite since my childhood. I love everything of this restaurant specially the ambiance, whenever I go those cabin rooms makes me nostalgic.
I have tried biriyani from many restaurants but for me royal is the best, once you try you will never forget the taste and smell of biriyani. And the quantity is also good.
And you will get a very gentle and comforting behaviour from everyone who works in there.
Not only biriyani the have all much more delicious items like chicken - mutton chap, murg-masallam and many I must say every cook have magic in their fingers. And one very great tips from myself doesnt matter what u have order but in the end always end up with a firni. Once you have tasted it you will automatically get a feeling like this sweet came from haven thats for sure.
Btw enough said feel just go and try.
