Seek frantically after facilities for gander (4-3)
I believe the answer is:
look-see
'gander' is the definition.
(I've seen this before)
'seek frantically after facilities' is the wordplay.
'frantically' is an anagram indicator.
'after' says to put letters next to each other.
'facilities' becomes 'loo' (I've seen this in other clues).
'seek' with letters rearranged gives 'ksee'.
'ksee' put after 'loo' is 'LOOK-SEE'.
'for' is the link.
(Other definitions for look-see that I've seen before include "Inspection (colloq.)" , "Dekko" , "Young's - relates stress and strain (Physics)" , "Brief inspection" , "Survey, inspection" .)
