Paris or Rome? Excellent! (7)

I believe the answer is:

capital

I believe this is a double definition.

'paris or rome?' is the first definition.
(I know that Paris is a national capital)

'excellent' is the second definition.
(I've seen this before)

(Other definitions for capital that I've seen before include "Major city - investment - excellent" , "Upper case city" , "A big letter, or a big city" , "liquid assets" , "City - finance - very good" .)

I've seen this clue in The Times.
