I didn't manage to go to all the places I had been planning to go. I wanted to visit more restaurants but I went to many shops with vegan products instead. I also bought some second-hand stuff on flohmarkt.
I found a vegan bistro by mistake. The food was very simple and everything was animal-free.
In a Spanish restaurant the only vegan dishes were appetizers.
Thare are many organic and health food shops in Frankfurt with a lot of vegan products. Here is what I bought.
