Hi Frankie,
look here:
http://www.bundesfinanzministerium.d...ser__saal.html
Apparantly Göring was present at his Ministry only on rare occasions, so he had no real office (So says the current owner of the building, but to be honest, I can hardly believe this. Guess the federal finance minister uses it now, but they won't tell.

). What could be associated with Görings preference of representation though, was the "Grosser Festsaal". Nowadays it is used as a conference room.
Cheers,
Christian
