This is a _great_ small diner with a very traditional feel, complete with décor heavy on steel, white Formica, red vinyl, and white tiles, all of which somehow feels natural as opposed to forced or fake. The diner is kept clean, and it is bright from lights as well as large front windows. License plates on one wall represent all 50 states. (I believe they could use a DC "Taxation Without Representation" one if anyone is heading this way and has an extra one. :-) ) Two tvs are on the walls. And as others have said, there're only around 20-30 seats at tables or the lunch counter. The staff is warm and friendly. The food is very good and has great prices, all from a large menu with lots of breakfast, lunch, and probably dinner items. (I was hungry and not focused on the latter, so it didn't register.) I thought the peppered bacon was particularly excellent.
I hope I have more chances to visit!
