The one restaurant I recommend in West Union, IA, is the Barrel Drive - In. Its location is easy. It is found near the main crossroad from the Market, gas station, and right next to a motel.
I have ordered there before. They keep the order simple. Arriving and parking in the Barrel, I wait for the waitress or waiter to come. The workers aren't super happy, but they are pleasant and nice.
One problem, I have notice was that some times the Barrel closes their phone, making it impossible to order.
Another problem is the road. The drive way in and out is a bit rough and difficult to manuvuer.
There two are the only problems I have notice and both are irritating, but it is worth it to eat tasty food.
The Barrel is open in the spring to fall. They shut down in the winter. They stay open till 9:30 pm.
The main food is fried chicken but there are varieties of other orders.
If you have ordered, they will bring it on time. Bringing the food home or eating there, the food is delicious. Especially the fried food.
