'dolcelatte?' is the definition.
I can't judge whether this defines the answer.

'dismal revolutionary beginning to explore london area' is the wordplay.
'dismal' becomes 'blue' (I've seen this before).
'revolutionary' becomes 'Che' (Che Guevara the Marxist revolutionary).
'beginning to' says to take the initial letters.
'london area' becomes 'SE' (postcode for south east London).
The first letter of 'explore' is 'e'.
'blue'+'che'+'e'+'se'='BLUE CHEESE'

'for' acts as a link.
