Don't know, but here's a "Frederick, MD" story.
When I was in grad school in New Mexico, I drove from NJ to NM several times. On my last leg driving east back to NJ, I decided I would only eat "Reuben" Sandwiches.
By far, the best Reuben I got during the trip (and I believe the best one I ever had) was at a place in Frederick, MD called "Joe's Diner". I think it's closed up now (this would have been about 12 years ago). But it was new-ish at the time, decorated in 50's retro. All the food was pretty good there.
That's all I got for this thread.
