Awesome food ..definitely try the kasturi Kebab (which is an egg based chicken kabob) and the Sikandari raan. Also have the dal makhni as its very creamy and delicious..
Also the rotis are gigantic so 1 roti is good for 2 people. Try the Lacha parantha and missy roti. In addition their Phirni and Flambe galab jamun are amazing.
