Potrefena Husa is a chain of restaurants serving Czech cuisine and beer. I've been to Potrefena Husa Resslova twice, both times the food and atmosphere were excellent. My personal favorite was "Svíčková na smetaně", which is a traditional Czech dish. I definitely recommend to pay a visit if you're anywhere near the Dancing House. Unfortunately, can't say the same about Potrefena Husa on Platnéřská, which is closer to the center and is very tourist-oriented, it's a bit more expensive and the food is not as good compared to Resslova, at all.
