Walrus is right...
Sam Smiths from the Bricklayers Arms (Off Tottenham Ct. Road. London)) is palatable and still very reasonably priced. SS's bottled Nut Brown Ale, Porter etc. are all quite drinkable too.

On Draught, it does vary, but at £1.60 a pint, I would probably drink dog's whizz and like it.
