Chłodnik litewski, Lithuanian chilled soup is another thing I don`t eat. Soups must be hot, that is obvious, so eating cold one is a misunderstanding to me.
I agree, cold soup is useless!
Most Poles share our view. I remember eating that cool soup as a child a few decades ago but later on I have never seen it anywhere. It is on the menu of quality restaurants but I am not sure about popular, cheap places.
