Chai free to be served regularly here (4)
I believe the answer is:
cafe
'chai free to be served regularly here' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for cafe that I've seen before include "Alate" , "It's an eating house - face up to it" , "Place to eat" , "Greasy spoon" , "A small restaurant as in France - face up to it" .)
