I also forgot about the "R" House, its spendy but if you want a good dinner its a great place to eat, especially if you'll have the wife or gf with you.
If you do go out to the Oregon Cave's or just want a damn good breakfast stop at Taylor's Sausage in Cave Junction.
Cave Junction is a **** hole with a bunch of 100% grade A white trash and druggies, so I never stay there long. But Taylors is where my family down there takes all their deer, elk, etc to butcher and they make some great food in their diner.
