I went Berlin last week. I ate Chill con carne with bread. Also I tried something I haven't taste before. Potato and cucumber with fresh dill source hot pot. Hot cucumber was very strange. I wasn't sure if I liked it or not.
Octopus burger at White trash first food, Shonhauser allee 6 Mitte. The octopus was way bigger than I thought but it was very soft and yummy. Recommended.
Cats and mice mash-marrow. You probably imagine how it tastes like. It's nothing special than the look of it.
