Food one consumes at the hotel (4)
I believe the answer is:
hash
'food' is the definition.
(hash is a kind of food)
'consumes at the hotel' is the wordplay.
'consumes' becomes 'has' ('have' can be a synonym of 'consume').
'at' says to put letters next to each other.
'the hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'has'+'h'='HASH'
'one' is the link.
This may not be correct. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for hash that I've seen before include "Drug" , "chop into small pieces" , "Meat dish or hallucinogen" , "Meat dish; mess, jumble" , "Keypad symbol" .)
