Eat'n Park has been a part of my diet since I turned 16 years old and they were one of the only 24 hour joints in town. And if there was ever a Pittsburgh staple that needed some "refreshment," this was it.
Fully remodeled locations, a fresh menu with plenty of their classics, low prices, and still 24 hours. All I have to say, is kudos to them as they did the transition fairly well.
Ultimately it's still just a 3 star establishment, but I don't say that in a bad way. You'll get a good, cheap meal, and typically good service. Plus, you can't go wrong with a milkshake, smiley cookie or grilled stickies.
