My husband I were looking for a healthy place in Cologne for dinner. We found oshos delicious and exactly what we were after - healthy and affordable. There is a cafe and a restaurant next to each other both called oshos. The staff were really friendly and helpful. At the restaurant they had a main dinner meal which was quiche, rice and salad or you could choose your own vegetables and they charged by weight. There were plenty of tables available but was also busy. This is a vegetarian restaurant with vegan options. They also serve alcohol. It is a bit of a distance from the main cathedral but certainly worth it! We will return if we are in Cologne agaim.
