I found Hanz und Franz accidentally while wandering around in the neighborhood. I did not expect to find a vegan friendly restaurant in the area!! :-)
They serve a few dedicated vegan items including a vegan desert (along with traditional German meat food for your non-veg friends). I did not particularly like the vegan desert (an orange/vanilla custard type dessert) - but I was still thrilled to be able to eat desert in a restaurant!
When my partner and I both ordered vegan dishes, the waitress asked us if we were vegan so that she could bring us a special vegan bread appetizer (delicious garlic bread!).
Prices were good, house wine was good, I will definitely go back!! (If they start offering more vegan main courses and more vegan desserts, I might stop cooking all together :-)

Cons: not enough vegan desert options
