I used to live in the building above Jonas and never realized I had such a gem of a restaurant beneath me the entire time.
I've thoroughly enjoyed every meal from there, and you can't beat a family owned place. They are so friendly and accommodating.
Favourite dishes are:
Chicken Paprikash - this is a difficult dish to make at home, I've tried it and it never quite tastes as good as it is at Jonas'
Chicken Schnitzel - this is authentic schnitzel, its large, flattened and thinly breaded. The potatoes it comes with are to die for.
