Really likes to dine where there’s just space for two (4,4)
I believe the answer is:
love seat
'where there's just space for two' is the definition.
'really likes to dine' is the wordplay.
'really likes' becomes 'loves'.
'to dine' becomes 'eat' (I've seen this before).
'loves'+'eat'='LOVE SEAT'
(Other definitions for love seat that I've seen before include "furniture item" , "You should get your mate in here!" , "chair" , "Armchair for two" .)
