"Keystone Restaurant is the definition of a classic diner — right in the heart of downtown Harrisburg, just steps from the PA Capitol. This was a perfect breakfast stop on our way to Gettysburg. We went with some of the popular choices: the 3 eggs Western omelette with cheese and an English muffin on the side, biscuits smothered in sausage gravy, and of course, I couldn’t leave Pennsylvania without ordering scrapple (had to make my son try it too!). Portions were generous, everything hit the spot, and the service was super friendly. One of those places where you eat really well for a great price. I’ll definitely be back next time I’m in Harrisburg."

"Excellent food! Pancakes were some of the best we've ever had. Service was friendly and attentive. I never ran out of coffee."

"First time here and I really enjoyed it. Cheeseburger on pretzel bun with chips was delicious. Excellent price. Waitress was really nice."

"Awesome place for breakfast. Very cozy open kitchen style, this ALL-AMERICAN diner is a perfect place for breakfast. Their staff is friendly and attentive. Their food is very tasty, a good variety of breakfast dishes. I had the three-egg omelet which was cooked to perfection."

"Hard to find a great omelette and coffee in a center of Harrisburg for a low price. This is the place for breakfast."
