The next place didn't open for over an hour so we decided to have another beer. Two of us order the Polotmavý and the other two the Tmavý.
The Tmavý was the better choice by far. It wasn't great but it was enjoyable. The Polotmavý less so. Very buttery and kind of muddled in the finish. It took a while to finish, which is good I guess, since it passed the time.
On the way out they had a chalk board with the beers and it turns out the Polotmavý was actually supposed to be an Alt, Thinking back I raised its mental score a few points. Still way to buttery to be enjoyed but I was evaluating as a lager, not an ale. It wouldn't sell in Düsseldorf but clean up the butter and it would be a passible brewpub Alt. Sort of explains the glass as well.
We still had some time to kill so we stopped in at BeerGeek Karlín. This is a bottle shop owned by the BeerGeek bar but they have a couple of taps and usually a lambic in a bag-in-a-box.
I was going to order the VIk Ležák as my next beer but it had kicked and was replaced with a sour. So I tried the Potmehůd Cascadian Dark Ale. It was very nice.
