I haven't done an in-depth research yet but want to venture into the reasons why this mall isn't working. It is a well-built grand mall. And this was captured at 6 in the evening!
Quite some time back, I wrote that a non-AC mall has a much better chance of survival. I think the same for Devarc. They must blow the roof off and let the natural air flow in. People will automatically flow in.
I sense there must be a certain ease to grandeur. In this age, grandeur alone cannot keep you in business.
