Advantage of setting up some Winnipeg delicatessen
I believe the answer is:
edge
'advantage' is the definition.
(I know that edge is a type of superiority)
'setting up some winnipeg delicatessen' is the wordplay.
'setting up' shows that the letters should be reversed in order.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'egde' is hidden in the letters of 'winnipeg delicatessen'.
'egde' in reverse letter order is 'EDGE'.
'of' acts as a link.
(Other definitions for edge that I've seen before include "marginal advantage" , "Lip; advantage" , "Periphery" , "Border or cutting side of knife" , "Border, fringe" .)
