Were there with the family and our friend from Ukraine. Well, the service was really good - can't say anything bad. But as to the meals...
Well, we ordered borscht because this is always a substantial soup. What they've brought us was slightly reminding me of one of my favorite soups: the beetroot was underdone, it was spicy (?), no sour cream at all... may be Polish borscht is served without sour cream but otherwise the taste is weird.
The main course wasn't anything special: sauerkraut, potatoes and schnitzel. The latter was pretty good though not outstanding.
Ziwyec beer is always good so we didn't want to experiment more.
All in all, the place is good, food is fine only if you know what to order and the service is nice.
Will I return there? Only in case other restaurants in the neighborhood (which I haven't tried yet) are closed.
