Keeling over, said to be legless in pub or restaurant (6)
I believe the answer is:
indian
'restaurant' is the definition.
(I know that Indian is a type of restaurant)
'keeling over said to be legless in pub' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
The remaining letters 'dian' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'or' is the link.
Can you help me to learn more?
(Other definitions for indian that I've seen before include "Delhi native perhaps" , "Eg, native of Delhi" , "IDA inn provided for this notionality" , "National" , "IDA inn provided for this nationality" .)
