Khazana at Boat Quay

This looks like a pretty old building. It is at Boat Quay behind the Singapore River. I was there early one morning. There were people just finishing a night of clubbing and having an early breakfast. I thought this building looks interesting. Behind on the right is the former ICA building. Khazana means treasury in Malay. What treasures does it hold? I am not sure, I think it is a restaurant.
