We did find a very nice place to eat in Susanville, CA. The Sage Hen Restaurant in front of the High Country Inn on Main Street. The owner/chef grew up in France and learned to cook there. He fell in love with a woman from Susanville and ended up moving there. His name is Serge Marchale. They get their beef from 5 Dot...a great purveyor. Our beef was cooked to perfection, the lentil soup was divine, and our salads of heirloom tomatoes/fresh moz.cheese/olive oil was refreshing. Our breakfast the next morning was delicious..although they were skimpy on the perfectly cooked hash browns.
Oh, my. The few times I've been there, Susanville really appeared to be a bit of a wasteland.
You can get way too much mediocre food for cheap at the Black Bear Diner. Avoid Champion Steakhouse. I guess when the mess hall at the maximum-security pen is your main competition, the bar isn't set too high.
Hopefully somebody can share a hidden gem. Not me. Good luck.
