KC to STL by car - What's good along I 70?
is the time frame that important? cause you're gonna be pushing it even driving straight through non-stop. many more interesting things along 50 (if kinda small-town burger shack-y) Sedalia, Jeff City, Linn, Union have quirky Mom n Pop places (JC has a German place that does a pretty darn good schnitzel, just hard to find named Stein Haus or something, largely hidden by a motel and gas station) but if you must take 70 NEVER speed through Boone County BTW (OT, I know)
Second to Shakespeare's. Good, solid Midwestern pizza.
Quite a bit more causal are the various Sub Shop locations in Columbia. Nothing too special, but they bake their own bread (the rye is especially good) and run the sandwiches through the oven to melt everything together. Very reliable.
They used to make their own potato chips, but it doesn't look as if they do any longer. Those were super special, served hot.
Highly recommend stopping at Les Bourgeois Winery and Blufftop Bistro.
It's in Rocheport, MO. About 10 miles west of Columbia and it's only about 2 minutes off I-70. The wines are surprisingly good. The food is very good. The views and the restaurant itself are also very nice.
Of course, I'll also give props to Shakespeare's Pizza. And while Booche's burgers are pretty damn good, i don't know that i would go out of my way to get them.
