Filmmaker Onir, who was on a visit to Karachi, loved the food and hospitality there, and hopes Mumbai becomes as pothole-free as the Pakistani city.

"One observation. Totally impressed with the pothole free roads of Karachi. Mumbai when will thee be potholes free," tweeted Onir.

Onir was there to attend The Social Media Mela 2012 to talk about crowdfunding, a method he used to fund his "I AM" series.
