Unlimited selection of food and coffee (5)
I believe the answer is:
latte
'coffee' is the definition.
(I've seen this in other clues)
'unlimited selection of food' is the wordplay.
'unlimited' says to take the centre (discard the edges or 'limits' of the word).
'selection of food' becomes 'platter'.
The middle of 'platter' is 'LATTE'.
'and' is the link.
(Other definitions for latte that I've seen before include "frothy cup" , "Espresso added to frothed steamed milk" , "Type of coffee" , "Italian word for milk" , "Frothy milky coffee" .)
