I don't remember having sour cream but there's a local place that I haven't been to yet that serves it like that. They had chives on top and meat in the middle. A little small and thin but very good. Also had some type of soup in a bread bowl (very good as well). The trip was amazing and I was planning on going to Ireland and then back to Germany for a few days for Oktoberfest in 2020 but then COVID hit. Trying to hit up the local Polish place with a friend, hopefully soon.
