Allsome! Let me know when you get yours set up and I'll be over there to help you break it in. Just remember, a pub is not a proper pub without a gaggle of cleavage bearing beer wenches.
I don't know anything about Harry Potter, but I thought it was Hogwarts in those books.
I was wonder how hot it would get in that thing, but I noticed that all the "pub patrons" are dressed like it's freezing out, and then I remembered it's in England. Isn't it always cold there?
Of course it's described in multiple measuring systems. A hogshead is 63 gallons (U.S.) when measuring wine, but 54 gallons when measuring beer, and 48 gallons when measuring ale.
The Hog's Head was the name of the pub operated by Aberforth Dumbledore in the village of Hogsmeade.
I showed the thing to my ten year old son, pointed out the dart board feature, and waited. He stood there for a couple of seconds then collapsed on the coach laughing.
