Not wise things to order in a restaurant? (7)
I believe the answer is:
noodles
'in a restaurant?' is the definition.
I can't judge whether this defines the answer.
'not wise things to order' is the wordplay.
'not' becomes 'no' (negative).
'wise things' becomes 'dles' (I can't justify this - if you can you should give a lot more credence to this answer).
'to' says to put letters next to each other (I've seen this in other clues).
'order' becomes 'o' (abbreviation e.g. in British honours OM, OBE etc.).
'dles' put after 'o' is 'odles'.
'no'+'odles'='NOODLES'
Can you help me to learn more?
(Other definitions for noodles that I've seen before include "Far Eastern food" , "Simpletons (colloq.)" , "Strips of pasta for soup" , "On instrument casually plays" , "Fools; pasta" .)
