Urges Cumberbatch, perhaps, to get food (4,8)
I believe the answer is:
eggs benedict
'food' is the definition.
(eggs Benedict is a kind of food)
'urges cumberbatch perhaps' is the wordplay.
'urges' becomes 'eggs' (I've seen this in other clues).
'cumberbatch perhaps' becomes 'Benedict' (actor Benedict Cumberbatch).
'eggs'+'benedict'='EGGS BENEDICT'
'to get' acts as a link.
(Other definitions for eggs benedict that I've seen before include "food" , "snack" , "something for breakfast?" , "Dish served on toast" , "Dish topped with hollandaise sauce" .)
