They had the Eisprom plombir which came in two flavours: Chocolate and Vanilla.
They are memorable because it is icecream in a wafer cone wrapped in paper.
According to this famous instagrammer they are creamily delicious like Cornish ice cream.
I definitely recommend them after trying them because they are so creamy and thick just like Cornish icecream.
As well as Eisprom Plombir, I discovered another brand which is just as good but I don't know which one is the original.
