'unheated wedding party?' is the definition.
The definition suggests a singular noun which matches the answer.

'unfriendly welcome' is the wordplay.
'unfriendly' becomes 'chilly' (I've seen this in another clue).
'welcome' becomes 'reception' (I've seen this before).
'chilly'+'reception'='CHILLY RECEPTION'

'at' is the link.
