Unlimited selection of food and coffee (5)

Here is my best explanation:

'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.
