Fighting in a beer hall? (6,6)

'hall?' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'fighting in a beer' is the wordplay.
I cannot really understand how this works, but
'fighting' could be 'strife' (I've seen this before) and 'strife' is found in the answer.
'beer' could be 'bitter' (bitter is a type of beer) and 'bitter' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
