Lunch stop Balestrand to Bergen

Not concretely.

I recommend to change the search to where is a power charging station and what are eating options around?

By the way: a good pre-packaged salad from a supermarket is always a good option.

Any reason why you prefer E39 to road 13 or little scenic detour from it?
Date of travel?

Thanks for your reply. We will travel the scenic route to Balestrand.

Just to re-check: you are driving via Voss and Vangsnes ferry to Balestrand? Therefore you will not drive the same route back?

Correct on the routes
