If you're still going to be on I-80 around a little town called Ogallala, Nebraska, a couple of years ago a friend of mine and I stumbled onto a small restaurant just North of the interstate called "Hoke's Cafe." If it hasn't changed, a really good mom & pop place with good food and price. And biker friendly. Riley, the cook is a bike nut, leaning towards Harleys, but still an OK guy. Parking lots on both sides of the building are gravel, so they encourage you to drive your bike up on the sidewalk under the front awning to park while eating. They have small signs "BIKERS PARKING" just below the front windows.
Well worth the stop there for good eats, at least it was 2 years ago.
IF I inserted the photo correctly, this is what the front of the cafe looks like. There's some other pictures inside the place at this website.
