A change of orbits can be refreshing (6)
I believe the answer is:
bistro
'be refreshing' is the definition.
I can't judge whether this defines the answer.
'a change of orbits' is the wordplay.
'a change of' indicates an anagram (the letter order is changed).
'orbits' with letters rearranged gives 'BISTRO'.
'can' acts as a link.
Can you help me to learn more?
(Other definitions for bistro that I've seen before include "Small French bar and restaurant" , "Orbits (anag)" , "Cheap restaurant" , "Small inexpensive eatery" , "Cafe/restaurant" .)
