tl;dr: Excellent.
Delicious food, friendly service, intimate atmosphere without blaring music.
We were there two days in a row, the first time due to my partner's food intolerances, and the second time because everything was just fine.
During this time we ate (or took away):
Butter rolls - great, expressive flavors
Corn soup - a surprising combination of sweet and spicy
Vegetarian burger with vegetable fries - fries on point, crispy and juicy at the same time, very tasty burger, although it would also work in a bun
Classic burger with sweet potato fries - fresh vegetables, delicious cutlet, great sauces and perfectly fried bacon, as a whole it tasted better than in most burger places I visited
Pizza - very tasty, although a bit small
Pizza rolls - with salami, ham, mushrooms and onion, a bit surprising, definitely worth trying (especially the option with salami)
The service was very nice, some dishes were prepared especially for us, and they were served very quickly.
Portions of the right size, filling.
Very affordable prices, although I am writing this from the perspective of a visitor from a big city.
Overall: it's worth it, regardless of whether you tolerate gluten or not :)
