It's not so much of a restaurant (and doesn't sell many food products), but Lucky Johnson General Store does sell coffee and some snacks. So, that's good enough for me.
This shop is the cutest with tons of West Virginia themed goodies to snag. And their coffee is locally roasted, organic and fair trade and can be purchased by the bag and brewed fresh. And, if you're lucky, you might snag a vegetarian/vegan snack.
Grab a delicious coffee, browse this sweet shop and get a cool piece to take home.
