Food from no ordinary urban quarter in unnamed European country (9)
I believe the answer is:
spaghetti
'food' is the definition.
(spaghetti is a kind of food)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for spaghetti that I've seen before include "Sort of food" , "A dish from the gas-pit" , "Pasta - Birmingham's junction" , "Strange tight peas for the Italian dish" , "involving a fork and many turnings?" .)
