When up at Seneca we always eat Front Porch Restaurant, good pizza and an awesome view of the rocks..Gourmet Express here is Grafton has good food, and also the lodge at Tygart Lake has good food with the restaurant over looking the lake.
Also have a place I have come to love called Drover's Inn located in Wellsburg. some of the best wings you will ever taste. The restaurant has a cool back story to it as well.
Four pages and no one has mentioned Coleman's Fish Market in Wheeling. Go tho the left side line and order the "Canadian White", and yes it is served on Nickles bread and wrapped in paper. And if you want tarter sauce it will cost ya an additional $.05. I have them in my phone and call ahead when ever I am passing threw. Trust me it is great!!
Fat Patty's in Huntington. Great food at an unbelievable price. Happy hour everyday. Buy one get one burgers on Tuesday. Pretty good beer selection for the area.
I'm originally from Huntington but my all time favorite place to eat is Rocco's Ristorante in Ceredo. It's an Italian place, but you can't go wrong getting anything from the menu. Their steak is easily good enough to eat without any steak sauce.
I recently went to pies and pints. It is a little further off 19 than the sign would suggest. Seemed like a good place but a little expensive. Otherwise i normally stick to the Morgantown area. Pugioni's is pretty good. Small intimate place.
