Kielbasa sausage... amazing. Golabki cabbage rolls are colossal but delicious. Beetroot soup broth was so good and comforting. I love their sauerkraut too! They make it mild and not too sour.
Yellow split pea soup is great - vegan and GF. They have GF flatbread but you can't do 1/2 sandwiches on it. Skip the sweet potato mash it is bland.
Get the ribs on rice in the pot with an egg on top (Dohl Soht Bi Bim Bap)! The chicken soup is also amazing. Even if you don't feel like BBQ you can find some seriously good food here.
