i watched RIO in 3D at CineStar...........i'd recommend that to you, plus the 3D experience is great, i wont say mind blowing but still its worth it. But ticket price of 3D movie is Rs 400 with Rs 150 for glasses!!
come straight from Akbar Chowk, u'll see a marriage hall called Al-Jannat Marriage Hall, ask anyone its very famous here then turn left (if ur coming from Akbar Chowk), head straight and u'll see CineStar.
