Time Out says
Lurking in the upper reaches of Radićeva, Valhalla bills itself as a heavy metal pub but is actually exceedingly mellow, an unpretentious pub-like alternative to the flashy places on nearby Tkalčićeva. It fills up on Friday nights but is at other times an ideal venue for a relaxed beer and chat. Well over a hundred varieties of bottled beer are available at any time, and there are usually eight or so brews on tap – the latter usually include latest runs from local outfits Zmajska, Nova Runda and the Garden Brewery, plus international stuff from the likes of London’s Brewdog. The background music is indeed of the resolutely riffing variety, but not so obtrusive that you can’t talk over it.
