The Center Cafe is located in Washington, D.C. It is part of the Union Station complex and situated on the main floor and you can't miss it. It offers plenty of seating and surprisingly the food was very fresh and the service was good.
During my visit or time I visited the restaurant, it was self-seating. The waitress quickly took my order and overall I had a very good experience.
I was there for breakfast The prices were very reasonable and offered quality given the choices of other restaurants in Union Station.
