I'm game mate. Bierkeller would, I think, be unwise on a Friday, unless you're tempted by a free shot of shit vodka/rum/whiskey/tequila with every drink. Be advised though, it's more of a metal night on a Friday - expect circle pits and goths aplenty. I'd be up for it - it's been too long since I had a good mosh, but it might not be everyone's cup of tea!

Filthy gash is absolutely right. I thoroughly approve!
