Newly-wed holding flower in restaurant (5,4)
I believe the answer is:
grill room
'restaurant' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'newly-wed holding flower' is the wordplay.
'newly-wed' becomes 'groom' (man who's just got married).
'holding' means one lot of letters goes inside another.
'flower' becomes 'rill' (I can't explain this - if you can you should give a lot more credence to this answer).
'groom' placed around 'rill' is 'GRILL-ROOM'.
'in' is the link.
Can you help me to learn more?
(Other definitions for grill room that I've seen before include "Place to eat" , "Where one may eat" .)
