Still another superb outdoor recreation restaurant is the Homeplace in Catawba, just a couple miles from Crosstrails B&B (owned and operated by Katherine and Bill Cochran).
The Homeplace is located in a lovely white clapboard house set on a green hill with a pond full of waterfowl nearby. For 20 years, it has been a phenomenal success, which proves that the road to making it big is paved with great food at a great price in a great setting.
Nearby are the Appalachian Trail and TransAmerical Bicycle Trail. The restaurant has the reputation of being the best place to eat on the 2000-mile Appalachian Trail.
The service is family style, and the cooking is country: country ham, fried chicken, mashed potatoes and gravy, green beans, brown beans, apples, slaw, biscuits, all topped off with cobbler and ice cream. It is truly all you can eat with no hard looks offered when you ask for seconds and beyond.
That should give you a pretty good idea and start on it. I've been there many times, as I have family in the area.
