One note: If your companion is not a Platinum Card holder the CL will cost $50. No more guesting (unless you've got a black card). So any time I'm trying to bring a guest in I go to UC.
I agree the Centurion food is not as good as it was, and not as good as other CLs, and I agree that the UCs (Rotunda in particular) are stepping up their game. Yet I still prefer the CL food by a lot. And neither is up to a standard I would find acceptable in a mid priced restaurant.
I was last at both a six days ago.
