So.....I have spent a fair amount of time in this general area, but not in Conrath in particular .
This is one of the more remote areas of the state, with very little economic development. Average household income is sub-$40k. I would strongly encourage you to ignore any restaurant ratings you see online, if you are using metro-Chicago standards of what constitutes a "4 star" review. They are just not comparable. And remember, the economic impact of COVID on areas supported by tourism (like this area is) was substantial.
Here's a link to the restaurant listing of the Rusk County Chamber of Commerce. This would be the place I'd start:

FYI,
