I used to stop at the Hen House Restaurant in Eureka, MO on my way back from college at Missouri-Rolla in 1979 - 1983. I enjoyed the food and atmosphere - friendly waitresses. Also, remember stopping at a Hen House restaurant south of Springfield , IL on a trip to Chicago in 1988. My wife and I both solved the wooden game with the golf tees on our first try and then spent the next 15 minutes waiting for our food trying to remember how we had solved it the first time. We still look for that Hen House every trip back to Chicago along I-55, although I'm not sure in what town it is located.
