This is a pretty standard breakfast restaurant like Perkins. They offer breakfast all day and the food is not too pricey. I have to say it is nothing too exciting, but it is a solid meal. While in Pittsburgh (from Cincinnati) visiting my brother, we initially went to IHOP (which I was pretty disappointed in because we can go to IHOP anywhere).
The IHOP was in a brand new development, with a huge parking lot, and a 45 minute wait. Luckily we decided to ditch IHOP and go to Eat n' Park two minutes away. There was no wait; it was not crowded at all, and it was part of a nice business district that reminded me of Northside in Cincinnati (somewhat, though not quite as cool).
I would have liked to go to a truly local restaurant (not a chain) in Pittsburgh for our last meal before leaving, but it was better than IHOP.
I don't really understand the name though. Shouldn't it be Park n' Eat? Oh well.
