Wow, their lunch set menu was impressive! It's short, so have a look before going, to see if you'd…read morelike it. But three plates of really good and high quality food, and also free bread and amuse busche. All for 114 PLN!
Dining environment was also fine dining style, albeit scandic/nordic - so no white tablecloth. Service was good. There's also some outdoor seating too, if the weather is nice, in a private small courtyard.
The quality of the food is almost Michelin star IMO. Won't be surprised if they do win a star one day.
Note that lunch is only on certain days. And dinner is a much more expensive affair...
