Unhappy about German city's educational establishment (8)

I believe the answer is:

sorbonne

I'm a little stuck... Click here to teach me more about this clue!

'educational establishment' is the definition.
The definition suggests a singular noun which matches the answer.

'unhappy about german city's' is the wordplay.
'unhappy' becomes 'sore'.
'about' is an insertion indicator.
'german city' becomes 'bonn' (city in Germany).
'sore' enclosing 'bonn' is 'SORBONNE'.

Can you help me to learn more?
