Aamir enjoyed the public reaction in person by sneaking into different theatres in the city.
"Well, I am very happy to see that people are loving this film so much. I am going from theatre to theatre to see public reaction. It's amazing to see houseful audiences laughing, whistling in the halls," Aamir told reporters at the success bash here Wednesday night.
"The work that Akshat, Abhinay has done is praise worthy and the actors too pulled off their vision very well. I am thankful to them for giving such a wonderful film," he added.

Buoyed by the success of "Delhi Belly", Aamir now wants to experiment with more unique ideas.

Every time I want to challenge myself doing unique films," said the 46-year-old filmmaker who produced films like "Peepli Live", "Dhobi Ghat", "Taare Zameen Par", "Jaane Tu... Ya Jaane Na" and "Lagaan".
The invitees at the party were friends and families of Aamir as well as the crew members of the film.
Actor Anil Kapoor and screenplay writer Prasoon Joshi were spotted, but they only came to meet Aamir and didn't interact with the media.
Surprisingly Aamir's filmmaker wife Kiran Rao was also missing. When asked about her, Aamir said, "She is not in town."
