When i went to Taman Anggrek Mall yesterday, there was a new event on the main hall, which is the advertisement of Spiderman 3 which should be available on movie studio starting next month (May 2007). Too bad none of us brought our camera, so there are no pictures of it, but you might want to see it by yourself by going to Taman Anggrek Mall. I don't go to the hall (i just went to Gramedia), so i don't know exactly what event they are holding on.
It's very common to see this kind of event in Taman Anggrek Mall. It seems that the main hall is never empty. They always had an event in this mall. It's interesting, since visitors will likely see different things when they visited this mall (unless you go very often, then you might see the same event for a few days before it changes to another event).
