It can happen that a guest walks in and thinks they have taken a wrong turn. There he stands, somewhat baffled by the absence of a reception desk which usually marks a kind of limit. He might even think that he has ended up in the wrong era and in the home of an eccentric lady from the previous century.
A patron of the arts maybe, given that the place is teeming with artwork.
However, he soon realises that this is quite real and now, maybe after catching sight of the business-suited men in the restaurant. Either that or the young people at the bar deep in conversation.
