Circa has great breakfast items.
You’ll get more than one meal out of a Heartland breakfast.
A real diner experience at the Chelan. Wouldn’t call the food great, but I enjoy going there once or twice a year.
Endolyne Joe’s is good too.
If you’re in any kind of hurry you’ll want to hold off on Meander’s or Easy Street. They’re both 1.5 hours easy. Meander’s because they’re so popular and Easy Street because, well, that’s just how it always seems to be.
