So there's a place in the underground pass between the train station and Planty called Kalejdoskop.
The owners are a family from Donetsk, and they serve Ukrainian home-made food.
The place itself is nothing fancy, a few tables and a bar
I've ordered soup with dumplings (sup z halushkamy) and dumplings with cabbage (varenyky z kapustoyu)
These things I miss sometimes in Poland, because the Polish pierogi are usually made with mashed potatoes+cottage cheese or sauerkraut+mushrooms, while Ukrainian varenyky are usually made with plain mashed potatoes or plain sauteed cabbage (fresh, not pickled).
The soup appeared to be not just with dumplings, but also with meatballs. It's been a long time since I've eaten something as good and tasty.
The "big portion" (12zl) is really big and is more than enough for a lunch actually.
But since I didn't know, after the "big portion" dumplings (15zl) I was fed up to the ears
I'll surely go for smaller portions next time (10zl/12zl correspondingly)
Central location, good Ukrainian food, recommended
