Riotous House as GOP reveals food delivery route (10)

I believe the answer is:

oesophagus

I'm a little stuck... Click here to teach me more about this clue!

'food delivery route' is the definition.
I can't tell whether this definition defines the answer.

'riotous house as gop' is the wordplay.
'riotous' indicates anagramming the letters.
'house'+'as'+'gop'='houseasgop'
'houseasgop' with letters rearranged gives 'OESOPHAGUS'.

'reveals' is the link.

Can you help me to learn more?

(Other definitions for oesophagus that I've seen before include "Gullet" , "Throat to stomach link" .)

I've seen this clue in The Times.
