I have fond memories of staying here about a half dozen times, although not since the latest renovation (and all after the previous one). At one point, I had top tier (of two) in their unpublished loyalty program. My first visit overlapped with Queen Elizabeth II and I saw her ceremonial arrival and departure as well as the special etiquette and security measures associated with her visit. I have a couple favorite suites on the Palm Court.

The current library was previously the business center. The Raffles store was located on the first floor near the wrought iron fountain, off of the Fountain Court.

From the pictures, my biggest disappointment would be the OP's birthday restaurant. I think it's the place where the tiger was infamously rumored to have been shot under a pool table. That piece of history has apparently been lost.

I'm also sorry to hear that the tiny Writers' Bar has been relocated.

BTW, one of the suites in the main building (not the Presidential Suite that the OP toured) was used in the movie Crazy Rich Asians.
