Lunch along Rts. 70/40 in central Ohio

My wife and I are heading to the Midwest in early April. We'll be driving mostly west bound on Rt. 70 while in Ohio, but may be able to spend some time on 40 as well. I definitely intend to hit Henry's in West Jefferson for pie. But is that also a good place to eat lunch? And even if it is, I'm thinking it would be wise to eat lunch a little earlier to give myself a little time to rebuild my appetite for the pie.
 
The only place that looks convenient among the restaurants reviewed on this site is Tommy's Diner in Columbus. Would that be a good choice for lunch? Any other recommendations for lunch starting about an hour east of Columbus would be appreciated.
 
Thanks.
