Looking at it again the broadest brush approach would be as follows

SW1A, E, H,P and Y - Westminster. The big area bounded by the river, Vauxhall Bridge Road, Grosvenor Place, Piccadilly to near Piccadilly Circus then down to Hungerford Bridge. A big chunk of this area is of course devoid of pubs.
SW1V - Pimlico. I know it includes Victoria Station but so be it
SW1 W and X - Belgravia. OK so Harrod's is in Knightsbridge but it's they who insisted on being in the same district as the queen.
