The thing i don't get about the Queens Grill restaurant, is that as a space, it actually wasn't as good as the two grill restaurants downstairs (was it?), with their floor to ceiling windows. They also had the advantage of being closer to the other public spaces
These photos also remind me how the Queens Room ceiling appears to have lost its ability to be multicoloured (or if it still can do this, I've not seen a photo of it). The clever ceiling was incredible in 1968, and it's complicated brass switch panel fascinated me.
