In an out-of-the-way industrial area, tiny Walhalla is a relaxed microbrewery that has quickly gained a reputation for its excellent beer. There are a few tables out front and the taproom has around 13 beers on tap, all named after gods, from the Loki golden ale to the Osiris farmhouse ale. Try a tasting paddle of four beers from €10.
It was set up after a successful crowdfunding campaign to get it up and running. You can combine a trip here with a stop at Oedipus Brewery nearby.
