We visited U Kunstatu on the recommendation of a friend (thank you Pete / Goatee!) and I can see why he likes it. It’s in a quiet little courtyard right in the centre of town and a nice place to relax for a nightcap although the beer range is limited (mainly bottles). They were happy to serve us outside but close to locking up for the night when we arrived so my score might not do it justice.

Right in the Old Town, this was a cool place. Only 3 taps, but an extensive bottle list. They have the option of sampling 6 beers for 350 Ck (about 16 USD). You can pick any 330-500mL bottles on the menu, which is a pretty cool option. Servers know the beers very well and are happy to make recommendations. Despite the high price, this place was awesome. Highly recommended.
Kind of modern-hipster beer bar close to the center. Service is good. Selection is filled with local craft, but only 3 taps. It is definitely one of the best places for local craft in the really center. Prices are not cheap. No food i think. Overall: ok, maybe too hipster tho.
(Visited April 2018) Nice beer bar in the Old Town, just a block away from U Tri Ruzi. Inside there's a big round bar, but interior is a bit bare. Nice outdoor area. Service was friendly and knowledgeable. Only three beers on tap, however good and interesting craft beers. Really good bottle selection, not huge but really well chosen with lots of interesting beers from some of the best contemporary Czech craft brewers. Well worth a visit, and you will probably be passing by on your sightseeing.
There was something unsettling in that place's interior, altough service seemed to be fair, and the selection was satisfying with that well-known bottles. 3 taps as well. The only thing that really disappointed me was the price of the beers. Really expensive place, despite the fact there wasn't anything in that bar you cannot find elsewhere.
