Chanakya Restaurant or The Cage Cafe
From what I know Balaji Tea Shop has now closed. But you must check out Samosa Hub over here as they do a CRAZY variety of samosas like Blueberry Samosa!
In Krishna Nagar you can visit Balaji shop. Here you can try Tandoori Tea, Pizza Parantha, Tandoori Coffee, Tandoori Maggi and many more amazing food.
Dont know much but tried tandoori chai there
