Driving from Jersey to DC
The Columbus Inn in Wilmington is a neat old place. You'd have to Google map for directions, but you just have to get off 95 for a few minutes to get there.
There's also another charming restaurant, a little less expensive, that's a bit further down the road that the Columbus Inn is on, but I can't remember it. Perhaps someone else can help - it's a red building with a bar in the front and the dining room in the back.
