I went to a cool one outside of the Youngstown area last year. Really cool! In the woods overlooking a lake with firepits, a dock and more. Classy but woodsy and fun! http://www.myrddinwine.com/Myrddin_Winery/Home.html
there's lots of them here in Coshocton County but i've never checked any of them out. Lots more in the surrounding counties and north of here in Amish country.
there's a ton of them around here. i've had to go to a couple for various meetings and functions, but i really don't see the appeal.
Raven's Glenn near Coshocton is very nice. Outdoor pergola dinning area on the edge of the Tuscarawas River. Great place to spend an afternoon relaxing by the river and their Sunday brunch buffet is incredible. Also YOLO Winery in Dover. Outdoor dinning area reminds me of a sidewalk cafe abroad.
