I was in Prague 41 years ago and had a couple of dark beers at U Fleku which I thought was the best dark beer in the world (and probably the best beer). Returning next year to Prague, I plan to visit U Fleku for a glass, but I plan to try other dark beers and pilsners (helps to have more money). Going through this forum, people had recommended Budvar dark and Kozel dark. How do they compare with the dark beer at U Fleku? Are there other dark beers to try? We will probably be staying in Old Town so we don't want to stray too far from the touristy sections.
