I like the concept of building an outdoor elevated area and filling it up with restos and dining places. Then put a big studio in the middle for events. Then use the lower part as parking area. That's maximizing space.
I don't think this area was meant to be for big crowds as the walkways are a bit narrow in most areas.
It also gets crowded when there are displays in certain areas. Avoid the Sky Garden area during rush hours or weekends. Better walk inside the mall or at the ground floor
