royal albert hall

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

'venue' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'somehow ally pally discovered other bar' is the wordplay.
'somehow' indicates anagramming the letters.
'discovered' says to take the centre (dis-covered - outer letters removed).
The centre of 'pally' is 'all'.
'ally'+'all'+'other'+'bar'='allyallotherbar'
'allyallotherbar' anagrammed gives 'ROYAL ALBERT HALL'.

'for' is the link.
