I think Sun Plaza in Sembawang is one of the most mismanaged malls in Singapore.
It's long due for at the bare minimum a new coat of paint and polishing of its tiles.
A decent makeover should at least be planned.
But given that it is under Koh Brothers and not Frasers or Capitaland, nothing will be done.
KBW! Do something for the Sembawang residents! At least have a decent mall for Sembawang MRT.
