Chalo Dilli is a road movie, which shows the journey of two persons Manu Gupta (Vinay Pathak) and Mihika Mukherjee (Lara Dutta). The journey originates in the dream city Mumbai, travels through the pink city Jaipur and concludes in the capital city Delhi. Like a few other films in the recent past, Band Baaja Baarat or No One Killed Jessica, Delhi has again played a major entity, adding up to a film's existence.
Mihika is an uptown investment banker, who is on her way to Delhi to meet her husband. Manu is a saree trader from Chandni Chowk, who is also travelling to Delhi. Due to some uncertain reasons, both of them are forced to travel together.
Manu is everything that Mihika isn't. He is loud-obnoxious-rude, whereas she is sweet-classy-well mannered. This can be the most mismatched travelling partners ever. Then starts a journey that will bridge up the gap between their cultural and class divide. It is the most bizarre journey through air, road and rail from Mumbai, via Jaipur to Delhi.
Though Chalo Dilli is derived form of Due Date, the writer (Arshad Sayed )of the film has imparted originality to the story by giving a total Indianized touch to it. The film is in whole a desi watch, with elements like dhabas, camels carts, deserts and train journey.
