Absolutely fantastic! Had one dinner there and a few breakfasts as we stayed in the associated apartment next door.
Anything we had was delicious, nicely served, tasty and didn't need to wait long. Not even during breakfasts when the place got packed.
I am gluten intolerant, had gluten free pasta and didn't have any stomach issues later. And it was sooo tasty!
Surprisingly, they don't offer gluten free bread, so I bought one in Biedronka and brought it with me for breakfasts. They were always happy to toast it for me. They even amended the breakfast meals so that they were GF.
The staff was always super nice, friendly, welcoming and caring.
The only thing I would add would be some light. :) The restaurant has very ambient lighting which is nice for dinner but I'd like it brighter for breakfast, especially the back diner.
Overall experience - fantastic!!! Bravo. Definitely recommend.
