Regularly heard in club restaurant (9)
I believe the answer is:
brasserie
'restaurant' is the definition.
(brasserie is a kind of restaurant)
'regularly heard in club' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'in' is an insertion indicator.
'club' becomes 'brassie' (brassie is a kind of club).
The alternating letters of 'heard' are 'er'.
'er' placed into 'brassie' is 'BRASSERIE'.
(Other definitions for brasserie that I've seen before include "bar in Paris" , "Caf" , "Simple restaurant" , "eatery" , "Where to eat" .)
