Terminal 1 at CDG may be horribly dated, but I love that design and look.
They had the "new" terminal, all of 3 gates. And then the baggage pickup area.
In between those areas was the "old terminal" it was this absolutely pristine 1960s ish airport waiting area that was hexagon shaped with this gorgeous black flooring also in a hexagon shape, a big brass compass in the middle, and everything in that area radiated out from that compas, the seats were lined up along the lines of the hexagon. Service desks, bar, etc. It had big tall windows (a few stories tall) so you could see out onto the runways.
Sadly it eventually was torn down when they renovated the entire structure for a new more modern boxy... thing.
