Food, large amount, seen in Biden's birthplace (8)

I believe the answer is:

scranton

'biden's birthplace' is the definition.
(Joe Biden was born in Scranton, Pennsylvania)

'food large amount' is the wordplay.
'food' becomes 'scran' (I've seen this before).
'large amount' becomes 'ton' (I've seen this in another clue).
'scran'+'ton'='SCRANTON'

'seen in' acts as a link.

I've seen this clue in The Telegraph.
