Feature of restaurant came first on bill: a pound off lodging (5,5)
I believe the answer is:
table dhote
'feature of restaurant' is the definition.
(table d'hote is 'the host's table' in French)
'bill a pound off lodging' is the wordplay.
'bill' becomes 'tabled' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a pound' becomes 'l'.
'off' indicates named letters should be taken away.
'lodging' becomes 'hotel'.
'hotel' with 'l' taken out is 'hote'.
'tabled'+'hote'='TABLE DHOTE'
'came first on' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
(Other definitions for table dhote that I've seen before include "Fixed menu with fixed price" , "meal; no alternative" , "With set menu" .)
