Newlywed crosses stream, finding place to eat (9)
I believe the answer is:
grillroom
'place to eat' is the definition.
(I've seen this before)
'newlywed crosses stream' is the wordplay.
'newlywed' becomes 'groom' (newlywed man).
'crosses' indicates putting letters inside.
'stream' becomes 'rill' (rill is a kind of stream).
'groom' placed around 'rill' is 'GRILLROOM'.
'finding' acts as a link.
(Other definitions for grillroom that I've seen before include "one may eat there" , "Where 6 may be served" , "Place to eat" , "restaurant" .)
