I have been to Valhalla! It was not full of viking warriors drinking ale, fighting and carousing, but a few tourists drinking beer and chatting. Maybe I got the wrong one - this pub in York is the one I visited. Wooden benches, fur blankets, flickering (medieval) lamps, runes carved into timbers, there was even mead served in horns. It was definitely characterful bordering on cheesey/comical,
