People are crazy with these bad reviews! Eat'n'Park is a Pittsburgh staple and a BREAKFAST/LUNCH spot. Don't come to eat'n'park expecting a fine dining experience: it's a beefed up diner.
The pies and breads are fantastic. They bake a lot of things in house. The breakfasts are delicious and their smiley Belgian waffle is the best waffle money can buy. The service is good at this location and it's open super late on weekends if that's your thing.
The salad bar is always fresh, the soups hot, and the sandwiches on the menu are good. Super clean and well maintained and a great location for a big crowd of people regardless of what time of day.
