The Science Centre itself is boring and outdated, unless there is a special exhibition like Human Bodies, there is nothing to do there, what a shame, it is such a waste of beautiful space.
However their dome Imax called ONMIMAX is always a great hit, every single movie I've seen in it was amazing. The experience is breath taking, I love the feeling of being inside the movie, it is way more fun than todays 3Ds. We sometimes go on Fridays for 9pm to catch a movie, the tickets are $13/adult, which is ok given current movie ticket prices at Cineplex are at $15 for 3D and OMNIMAX is waay better.
