Bit to eat, not cold, before a dance (5)
I believe the answer is:
rumba
'dance' is the definition.
(rumba is a type of dance)
'bit to eat not cold before a' is the wordplay.
'bit to eat' becomes 'crumb' (small amount of food).
'not' indicates named letters should be taken away.
'cold' becomes 'C' (eg on taps).
'before' means one lot of letters go next to another.
'crumb' with 'c' removed is 'rumb'.
'rumb'+'a'='RUMBA'
(Other definitions for rumba that I've seen before include "Ballroom dance of Cuban origin" , "Strictly round" , "South American dance" , "Cuban folk dance" , "one's on the floor for it" .)
