The restaurant is actually always busy. Therefore you should definitely reserve in advance. The selection is very good, the ingredients are fresh and the marinades are very tasty. Since I have celiac disease, I particularly liked that the marinades are gluten-free and my food was specially fried on a different pan. It was very tasty and we would definitely come back if we were in Cologne again.
In the future I would like to see clean bowls for the ingredients. None of these were completely clean. I would also have thought it would have been good if the waitress had come over and asked if we wanted something to drink, for example.
