"I'm quite a foodie and have a very Punjabi taste in terms of food. So when we were shooting in Delhi for the film, I used to eat a lot of golgappas, chhole bhature, dahi bhalle and meat from Karim's. Basically, I used to eat all the wrong things, but I loved that, " Sonam told over telephone from Mumbai.
In Rakeysh Omprakash Mehra's "Delhi-6", Sonam plays Bittu, an aspiring singer who lives in a conservative family in the crowded Chandni Chowk area and has a desire to break free from the typical Indian societal norms.
The one-film-old actress says a good amount of preparation went behind her character in the film in which she stars opposite Abhishek Bachchan.
"One has to really prepare for the role he or she is portraying in a film. For 'Delhi-6', I had to work on my accent, body language, clothes, my expressions, the way I walked and a lot of other nitty-gritty stuff, " she said.
Apart from Sonam's carefree Indian looks in the film, her performance in the hit peppy number "Masakalli", picturised on her and a dove, has been really appreciated.
"'Masakalli' is a beautiful song by A.R. Rahman and beautifully choreographed by Vaibhavi Merchant. Masakalli is the name of the dove in the film and it is very symbolic of my character. She nearly became my pet on the sets. She used to hop on to my head, " said Sonam, who is actor Anil Kapoor's daughter.
Asked if she was a wee bit scared of the bird, she said: "I wasn't scared of Masakalli at all. She was just a small bird. How could it harm me?"
The song has become so popular that a lot of Sonam's friends have started calling her 'Masakalli' and she finds it "really sweet".
Talking of her co-star Abhishek, the actress says she had a "fabulous" time shooting with him.
"We share a great chemistry. He is young, but experienced enough and he guided me and helped me through scenes where I would get stuck. Besides, we had great fun on the sets.
"Every 10 days we used to have a dance party when we were shooting in Sambhar in Rajasthan. We used to have a DJ who used to play really bad Hindi songs from the 1980s and 90s and we used to dance all through the night, " said Sonam.
