Involve first person, bringing them over to cook with top restaurateur inside (7)
I believe the answer is:
embroil
'involve' is the definition.
(I know that embroil is a more specific form of involve)
'cook with top restaurateur inside' is the wordplay.
'cook' becomes 'broil' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'top restaurateur inside' becomes 'em' (I can't explain this - if you can you should believe this answer much more).
'broil' put after 'em' is 'EMBROIL'.
'first person bringing them over to' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for embroil that I've seen before include "catch up" , "Involve (someone) in a dispute" , "In difficulties, involve" , "Involve or entangle in" , "Implicate" .)
