I went for lunch with 2 small children. Staff was very friendly and explained the menu. They speak very good English there. Lunch menu was starter (potato salad or gazpacho soup, main (enchilada wraps or oven baked veggies) and desert (apple pie or custard) for 10 EUR. Everything could be veganised for us, except the custard....we tried it all and it was delicious, fresh, homemade, healthy food, I and my kids really enjoyed. The place has a calmness to it. It is decorated with lots of recycled stuff.
You can buy some organic groceries there (but I didn't check what exactly).
Cons: Small Choice
