In place of wedding feast, a way to serve game (7)
I believe the answer is:
canasta
'serve game' is the definition.
'canasta' can be an answer for 'game' (canasta is a kind of game). I am not certain of the 'serve' bit.
'in place of wedding feast a way' is the wordplay.
'in' means one lot of letters goes inside another.
'place of wedding feast' becomes 'cana' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'way' becomes 'st' (abbreviation for street).
'a'+'st'='ast'
'cana' placed around 'ast' is 'CANASTA'.
'to' is the link.
Can you help me to learn more?
(Other definitions for canasta that I've seen before include "Can a staff cook stomach game?" , "Two-pack card game" , "Card game of the rummy family" , "Card-game, a form of rummy" , "Card game -- as an act (anag)" .)
