Crossword Genius

Illicit sort of coffee bar (5)

Ross

I believe the answer is:

black

I believe this clue is a triple definition!

'illicit' is the first definition.
(eg the black market)

'sort of coffee' is the second definition.
(black coffee is a coffee without milk)

'bar' is the third definition.
(to black certain goods is to boycott them)

(Other definitions for black that I've seen before include "-- Monday" , "It produces illegally undeclared income" , "What's written on in the classroom" , "Dirty" , "Extremely dark" .)

I've seen this clue in the Independent.
