Returning representatives assuming glamorous hotel serves popular mixed drink (8)
I believe the answer is:
spritzer
'mixed drink' is the definition.
(I know that spritzer is a type of mixed drink)
'returning representatives assuming glamorous hotel' is the wordplay.
'returning' shows that the letters should be reversed in order.
'representatives' becomes 'reps' (rep is a kind of representative).
'assuming' means one lot of letters goes inside another (inserted letters are taken in or assumed).
'glamorous hotel' becomes 'ritz' (I've seen this before. I am not sure about the 'glamorous' bit.).
'reps' back-to-front is 'sper'.
'sper' going around 'ritz' is 'SPRITZER'.
'serves popular' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for spritzer that I've seen before include "Fizzy drink" , "Wine/soda drink" , "Drink made of wine and sparkling water" , "Wine mixed with sparkling water" , "Ritz reps has drink of white wine and soda water" .)
