FA (Flight Attendant) reported odd smell in galley.  No smoke or heat.  Could not determine location.  Happened during descent profile into ZZZ1.  Ran immediate action item for smoke [and] fumes and then continued checklist.  As we turned off cabin electrics the FA reported the smell went away.  Flight deck crew conferred and elected to continue with briefed arrival with plan to immediately divert to ZZZ2 on our right at first sign that indications returned; as the difference in time to ZZZ2 was very short and would entail coordination/briefings that would entail a delay to make sure we did not miss anything.  Uneventful approach/landing ZZZ1.  Had FA show local Maintenance where they had smelled the 'fumes'.  Captain called Duty Manager for debrief.  Duty Manager conferenced in Maintenance Control to determine if smoke/fume checklist needed to be run.  It was determined to be not required.  Captain made electronic logbook entry into ACARS.  Local Maintenance briefed on position of switches in NON-NORMAL position based on checklist (we did not want to re-engage aircraft power at the gate by setting switches to normal termination checklist positions).  Local Maintenance told us to leave BATT SWITCH on as he had some checklists to run.
B737 Captain reported in flight notification by Flight Attendant of fumes in the cabin. Flight crew completed an uneventful landing after the fumes dissipated as a result of completing initial portion of the fumes checklist.
