European starts dancing at new eatery (4)
I believe the answer is:
dane
'european' is the definition.
(someone from Denmark)
'starts dancing at new eatery' is the wordplay.
'starts' indicates taking the first letters.
The first letters of 'dancing at new eatery' is 'DANE'.
(Other definitions for dane that I've seen before include "See 7 Down" , "One from Esbjerg" , "invader once" , "Great - - , dog" , "EU citizen" .)
