The one in Kennington? There's a Groupon offer which makes it look interesting, but the pics on the website look a bit grim. How much does a big ol' beer set you back at this place?

Anyone done a real Oktoberfest? And while we're on the topic, are those beerhall type places like Katzenjammers by London Bridge any good? I walk past it every day but have never been in, do they charge crazy prices?
