'eatery' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'host's scoffing a duck' is the wordplay.
'host's' becomes 'mc's' (short for master of ceremonies).
'scoffing' indicates putting letters inside.
'a duck' becomes 'donald' (I've seen this before).
'mcs' going around 'donald' is 'MCDONALDS'.

'in' acts as a link.
