When I went to Mannheim, I had lunch at the vegetarian restaurant Heller’s. It is very nearby the train station. You have a cold and a warm buffet, ingredients are clearly marked and you have vegan labels for quite a lot of dishes.
I had rice, carrots and some kind of vegetables pancakes. To be honest, I did not like it very much. It was not tasty and quite “oily”.
So I went to VogelFrei for dessert and I had a wonderful tart with lemon and almonds… so delicious. it saevd my day 🙂
