My colleagues and I stopped for breakfast at the Route 66 Diner en route to Clovis, NM (we'd spent the night at the Comfort Inn down the road). The diner recommended by the front desk wasn't open, so we stumbled across this place (which is apparently the original Route 66 Diner).
The two ladies that served us were polite and efficient service, the coffee was fresh and delicious, and the juevos rancheros were excellent. I'd recommend this place to anyone traveling through Santa Rosa. The music selection was also the perfect mix of old, classic, and new.
I've included a photo with this review. I admit that it doesn't look promising from the outside, but give it a chance.
