I'm doing a small road trip with my son in August to knock some new states in the mid-west on our quest to do all 50. Besides the sites, I am hoping to have some great food and used this thread as inspiration. We are starting in Nashville and ending up in Tulsa. Here is what I got so far:

Nashville to St Louis via Mammouth Cave National Park

St Louis - Bogarts Smokehouse

Kansas City - Joe's Kansas City Smokehouse

Betonville - (could not find any standout food options in NW AR)

Tulsa - Elmers

Am I missing anything good? Anyone familiar with the routes and thinks there is a place along the way worth stopping at?
