I went there several times and every time the food was really good. There is an "evening plate" which is Japanese style food with is a selection whatever is in season (changes daily) with brown rice and Miso soup. All strictly vegan.
The owner is also the cook is this small place and is very nice. He only speaks very few English, but I found out he named the place after his little family which is so charming.
My recommendation is the organic German Weizenbier with your diner and if you are still not full, have some of the cakes for dessert.
