Ox Yoke Inn definitely qualifies as a hole in the wall... located in the middle of houses and farm land, I cannot imagine anyone not local would even know about this place.
We went there for Mother's Day, and as expected it was busy. I opened the menu and found that things seemed a lot more expensive then they should be - and agreed after tasting the food. It was good, but nothing spectacular. No seasoning or anything.
And as an Iced Tea fan.. it seemed like I was drinking Ice water.
That said... there is not much in my area so I would maybe go again.
