Hand In Hand, Brighton (like someones front room, cosy and friendly with 'retro' Space Invaders video table)
Bristol Bar Kemp Town (lovely big windows, colonial feel)
North Laine (ex Gloucester nightclub, nice vibe, own brew).
I'd back the usual suspects like the Lewes Arms, Selden Arms, and Basketmakers.
But possibly the best pub in the world which I visited last year, is The Square and Compass in Worth Matravers, near Swanage. Cider and ale served through a hatch from barrels, owned by the same family since 1900, only food home made pasties, view of the sea from the beer garden at the front with chickens circulating around your feet, geology museum attached, I could go on and on - utterly wonderful and unique.
