...and on the seventh day he rested. Are you kidding, these beers don't drink themselves!
I started off trekking down to Mrtvá Ryba, a student pub near the Charles University Botanical Gardens. It is not well marked from the street. They have a nice patio and is fairly shady with all the trees.
The three fixed taps are Pivovar Biskupský Děkan kvasnicová 11⁰, Štěpán 12⁰ and Albrecht Tmavý 12⁰
I went with the Štěpán 12º. Very tasty.
