I visit this place for breakfast a couple times a month. For the most part, the service by the morning breakfast staff is very fast. The food won't win rave reviews, but it's no worse than that of other places in the Harrisburg area, is reasonably priced, and is usually served hot. The morning staff are mostly regulars that have been there for a long time, and once they get to know you will kibbitz with you when they have a moment. As far as lunch and dinner, I've tried them a couple times, and the previous reviews are pretty much on the mark...I doubt I'll return anytime in the forseeable future for lunch or dinner. I'll stick with breakfast.
