Restaurant in Joplin, Missouri
You might try the Red Onion Cafe. It may have the best food.
One place I have on my list to try is Cafe on the Route in Baxter Springs.
If you wanted a couple of places that are truly Joplin ---
Fred and Reds-all they have is chile, tamales and hamburgers. My favorite is tamale deluxe. You eat it with crackers, which come heated. The seating is very limited though.
