This is essentialy the only cafe in Nikiszowiec, but it's excellent. The location is lovely, on the…read morecorner of the main plaza, and the very pleasant decor is laid out in something resembling airy french provincial. The young waitresses all seem to be in wonderful moods, and (at least the one who served me) spoke perfect english.
Facing the side street Byfyj has a bakery, and the cafe/restaurant main has more very enticing cakes. But on this hot day I was too hungry for cake and ordered a cold gherkin soup (trust me - you should try it sometime in Poland!). I imagine service could be slow if there's a lot of customers, but thankfully, I don't think big tour buses make it here.
I'd definitely recommend trying out Byfyj on your stop in Nikiszowiec.
