There are several little restaurants on the road...they are all quit good and cheap !
I really like the gnocchi with creamsauce.
Try their local strudel.....with apple, raisins and some nuts.
Very heavy.....so try to make some space in your stomach.
Its on the way to Triglav, in Kranj area. They mix local food with international and make the greatest asparagus soup that I tried. The family is very nice, their young sons as well as the father have been through ENOLOGY course and can reccomend the best wines in the area. The atmosphere is nice and cosy and they have parking available. IN the summertime it is also possible to sit on the terrace. I love their large vase filled with all the wine bottle corks :)
Favorite Dish: I recommend All! cant make up my mind :)=
At the entrance of Vintgar Gorge, and at the Šum waterfall (the last entrance or exit, depends where you started first) there are cafes serving refreshments.
So, sit down for a few minutes & enjoying the sceneries around you.
Get a great hot meal at the huts. You don't have a big selection, but I was quite happy with the food.
Favorite Dish: I had some Bohinj Sausages that were a delicious lunch, and one dinner I had a great maccaroni with meatsauce meal
