No friend will ever tell you again you can't organize a piss-up in a brewery. You'll gain a lot of respect from your friends after bringing them to this fully-functioning beer factory.
But wait! Here's the best part - after learning how the beer is made (a tour is given by a genuine beer master), and watching the traditional production process, you'll all get to taste exceptional kinds of freshly-made beer: Light, Dark and Wheat. First tasting - 3 small glasses each, then a proper PISSUP - 3 extra large glasses of the beer of your choice for each lad.
Brewery is in the city centre, so transport is not included - or needed!
