Thoughts on German breakfast culture and my favourite French delicatessen shop in London

I have always been fond of breakfast time. I even feel like after having lived with friends and the prince of sun in London and Brazil that German culture compared with the latter literally celebrates breakfast, especially on Sundays.

A German proverb even has the following diet suggestions:"Frühstücke wie ein Kaiser, iss zu Mittag wie ein König und nimm dein Abendmahl wie ein Bettler" ("have breakfast like an emperor, lunch like a king and dinner like a beggar").

So what's part of a typical Baden-Württembergian German Sunday breakfast?
