The only one in central London is Bunker, and honestly it's not worth it. If you're in Covent Garden go to The Harp instead. If you're around Borough, there are far better places to drink than Brew Wharf, like The Rake and The Market Porter.
But, if brewpubs are your thing, just note that since I wrote that article, The Cock & Hen has ceased brewing, and a new brewpub has opened at the William IV out in Leyton.
