For a good homestyle meal get off at the Middlebury exit in Indiana maybe it is 116 I forget.Go thru Middlebury to route 20 and turn right about a mile for Das Essenhaus.Amish/Mennonite style meals.You will eat enough there you can make it to the other end of the trip.
I wasn't a geography major but I don't believe I - 80 goes through Michigan. I can help with the exits near Toledo if you're interested. What are you looking for anfd how close to the interstate do you want to stay?
As I recall, there's a great Lebanese restaurant on Reynolds Rd. in Toledo north of exit 60 called Byblos -- go north maybe a mile and look for it on the left. Is it still there? You can eat yourself silly, and it's all good.
Byblos is good but it is more than a mile from the turnpike exit. Another possibility is Loma Linda, a Toledo institution located a little east of the interchange at Toledo express airport, fun, inexpensive tex-mex.
