Another option for quick lunch close to work. Hitra žlica – quick spoon as self-service restaurant offers traditional slovenian cuisine, for most dishes you need spoon.
I ordered beef stew with buckwheat porridge, got a piece of bread on side (7€). Portion was huge and meal was tasty, even I am not fan of buckwheat. Service was quick and helpful. All that for loe price.
So if you are looking for quick traditional meal in city center for cheap this is good option.
