How do I access the hidden bonus dungeon?
1. Beat the game and save your cleared game data.
2. Load your cleared data.
3. Visit the Ruins of the Dragon Race and view the scene.
4. The Leaf Tower will be available on your world map, in the north of Albion. It's invisible until you mouse-over it.

That's the grand equivalent of the staff room. Once finishing you unlock an extra menu with discussion (well, monologue) by the voice actors as well, but those haven't been translated (seeing they're only audio, and not really relevant to the game). You don't unlock any extra cgs depending on your playing statistics like you did in Uta.
