Have visited many of the Potrefena Husa’s around Prague and I find them all reliably good but the one at Ressolva is my favourite, the brick vaulted ceiling gives it a more traditional atmosphere than some of the other outlets. Visited here twice on my most recent trip. On my second visit, for dinner, I had the beef tartare (fabulous!) and the pork schnitzel washed down with some lovely unfiltered Staropramen’s, this was easily the best meal of my entire visit to Prague. Service was very good and the toilets are always spotlessly clean.
