I used to love Forum when it wasn't a general thoroughfare. Nowadays, there are so many people walking through that you wno9der whether they are just using it as an air-conditioned means of crossing over from one road to the other.
The food court is so noisy that you can't talk properly. i would prefer Sigma Mall's food court anyday.
And the place is one huge mess when it rains outside.
Not the best of places to hang out unless in a big boisterous group!
