Restaurant in old club welcoming queen (9)
I believe the answer is:
brasserie
'restaurant' is the definition.
(brasserie is a kind of restaurant)
'old club welcoming queen' is the wordplay.
'old club' becomes 'brassie' (brassie is a kind of club. I am not sure about the 'old' bit.).
'welcoming' indicates putting letters inside (in sense of 'inviting in').
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'brassie' placed around 'er' is 'BRASSERIE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for brasserie that I've seen before include "Simple restaurant" , "eating place" , "eatery" , "bar serving food" , "Caf" .)
