The beer is free flow with the beer spa at only 690 CZK for 20 minutes, but then again a pint only…read morecost about 35 CZK or roughly €1.20, so it's like 20 times more, so unless you must be drinking a pint a minute from the barrel by the bathtub for it to be cost effective and/or you hate baths, this ain't for you (I really need to get one of those! It feels so princely with a wooden barrel of beer by your bathtub). Also the beer is rather foamy, maybe because I don't know how to tap beer, but I spat all those foam into the beer bath, so it's no lost either! Also be early for the massages which are very affordable!
